A sea of bluebells have suddenly flowered on a hillside on Exmoor for the first time in hundreds of years.
National Park officers believe the plants have lain dormant at Bye Wood, near Winsford in Somerset, for centuries. Clearance work has been going on since last year to create new woodland. As a result, the disturbance has prompted the ancient bluebell bulbs to start sprouting and suggests the site was once completely tree covered.

World's biggest plant discovered off Australian coast
The largest known plant on Earth - a seagrass roughly three times the size of Manhattan - has been discovered off the coast of Australia.
Using genetic testing, scientists have determined a large underwater meadow in Western Australia is in fact one plant.
It is believed to have spread from a single seed over at least 4,500 years.

Houseplant from Aldi and Tesco that can keep flies away all summer for just 67p
Flies hate one particular plant that you can pick up in your local Aldi or Tesco. Basil repels flies as they hate the strong smell.
...
Mint is also said to keep flies away
...
If your kitchen has fruit flies, you should half fill a glass with apple cider vinegar and cover it with cling film and poke small holes into the cling film.

Does one need to bruise the basil or mint to release the scent?
That's often the catch with using the smell of plants - they have to be damaged. It's not always the case.
How about a solar powered plant pot/frame that gradually crushes/agitates the plant growing in it, thus providing a constant smell.

Is it time we ditched the word 'gardening'?
The botanist James Wong has caused a hoo-ha by suggesting that we should consider ditching the term "gardening". I know, I know, but bear with. The g-word, he says, is loaded with "cultural baggage" and if more young people are to embrace (trigger warning!) "gardening" we may need a term that is more "inclusive".
https://www.theguardian.com/lifeandstyle/2022/aug/28/james-wong-on-gardening-is-it-time-we-ditched-the-word-gardening-
(warning - article behind a plea wall)
Maybe the term "gardener" has already been used too much, so people need a new term for their hashtags, like #plantdaddy. I assume getting a hashtag is rather like getting a gmail account - put in your suggested name, it's rejected because someone already has it, try another, and another and another.
Some PBS list members have similar "handles" to those hash tags. More difficult to scrap the noun "garden".

Japanese knotweed is on the noxious weed list in Oregon and probably also in Washington State. It can be killed. The problem is with the use of glyphosate, although other methods work with a little patience. I had some 30 years ago in the Willamette Valley where I lived and I succeeded in eradicating it, as I did with a large clump here on the coast.
But it spreads quickly and getting rid of large amounts is problematic... The polygonums or whatever they're called these days are a large, nasty and diverse genus... I don't even want the an ornamental species in my garden because the genus leaves such a bad odor.

Flower with 'dead rat' smell blooms in UK garden
Bulbophyllum phalaenopsis is emitting its delightful aroma at the Cambridge University Botanic Garden.
The plant, from Asia, flowers every three to four years but "it's very rare to see it in flower outside its natural habitat", the university garden said.
The "total stinker" is irresistible to carrion flies which pollinate it.
https://www.bbc.co.uk/news/uk-england-cambridgeshire-63416265
So plants that are pollinated by flies in the main don't smell pretty? I have both Scoliopus bigelovii and S. hallii which are clearly pollinated by tiny little flies but I've never detected any odor at all. Where these little flies come from, when I don't see them anywhere else or on other plants, always amazes me. I'm assuming that means at least the flies smell them!
I am an aroid fan, no matter the "scent".....
That said, there are plants beyond number that have neither scent/smell nor copious nectar, for which we know of no specific pollinator, or how/why they do the deed, albeit we humans do not have the senses of invertebrates, or even very many vertebrates (ever smelt the pheromones of a moth?).
Nature is indeed a wonderful thing.
Geophytes flowering in the Atacama desert:
https://www.theguardian.com/world/2022/oct/29/desert-bloomed-in-chile-atacama-driest-place-on-earth
Article does mention "geophytes" but does not specify. Drat!
Every few years, more than 200 species of plants bloom, producing a spectacular carpet of purple, pink and yellow flowers on the desert floor. Many of the species are endemic to the area, including nolanas, huillis, and añañucas.
The article could / should have been better. If they are good enough to say "geophytes" rather than "bulbs" they could / should have been specific.
I had seen the two sentences you posted, CG100, and previously (before posting the link) had done a Google search. For añañucas it brings me to hotel information. There is also a line of images that look rather like Rhodophiala. Nolanas are an annual. Nothing on huillis.

O.K. I'm confused. Here's a link to an article about growing saffron in Kashmir. Indoors!
https://apnews.com/article/business-india-kashmir-climate-and-environment-ceb197472c72837ff001b001f4939826
However the numerous photos show the entire flower being plucked. And I used to read that the high cost of saffron spice is in part due to the intense, meticulous labor of plucking the stamens from the flowers.
I expect that flowering saffron indoors is similar to forcing bulbs for early spring bloom. But do the corms regenerate sufficiently for repeat production is subsequent years? Or is this a once and done situation. What's your opinion / thoughts / comments.
I think the key here is growing them indoors. I have been thinking about looking for bulbs to trial indoors at my department CEA greenhouses, as well as in my home aquaponics system. I had a couple of glads in ebb and flood LECA beds (3'x4') and in 2 years I had so many corms I had to empty the beds to remove them all.
In general, I think of gladiolus (and other crocus species) as easier to grow than Crocus sativus. Greenhouse is lighter / brighter situation than the grow racks in the pictures. Which don't even appear to have grow light units.
Just call me curious. And if curiosity killed the cat, remember that satisfaction brought him back.
Growing stuff indoors is something they like to demonstrate these days. It's often shown on the TV - how to produce salad crops in the centre of big cities. I tried and could not grow saffron crocus to flower here - too dark, cold, whatever. From the text of the article it appears growing saffron in the wild is becoming difficult and that has driven them indoors. That would mean they were not flowering the bulbs indoors one year and then letting them recover in the wild, or bringing in new plants from the wild.
There is a town in England "Saffron Walden" famous for growing Saffron in the middle ages. Not a thing now, but seemingly due to the cost of picking the crop, not climate change.
There's all sorts of totally crazy information online. To wit: hydroponic vertical saffron farming, with roots in a nutrient rich water solution rather than soil. Considering that one of the images in that article is of Crocus 'Pickwick' a popular spring flowering hybrid crocus I am not too sanguine about the accuracy of their information.
Saffron has been grown in Pennsylvania by the Pennsylvania Dutch / Mennonites. It was grown somewhat commercially into the 21st century, I believe, but not currently.
The indoor period should be only for collecting the pistil, the corms should be going to be planted after that.

Hi David. For the last 15 years I have been involved with growing veggies of all sorts (fruiting and leaf) in greenhouses which is what I am referring to, not in my house. (Though the glads were in my backyard aquaponics system in LECA).
I have my reservations about the vertical farms with sole source lighting really working on a commercial scale without venture capital spending, but a proper commercial greenhouse with supplemental lighting can produce single or rotating crops year round.
To see a successful business look at Gotham Greens. Once a small rooftop greenhouse in Brooklyn NY the company has something like 7-8 very large greenhouses spread over the US.
Potted flowering bulbs grown as cuts or in pots have been grown in substrates for a really long time. All it takes is time and a market to figure out how to do it. With my upcoming retirement, seems like a great backyard project.
Peter - thanks. Greenhouse might mean natural light and vertical artificial light.

Oh, that's not what I consider vertical gardening. The plants are growing on horizontal shelves.
A few years ago there was a lot of true vertical gardening, much of it outside, and popular in one country in particular. Memory fails here. I think they were covering walls with fabric pockets.
The one question I always have about hydroponic and/or vertical gardening is this, and I do not see it addressed. Supposedly, the soil mix and added nutrients replicate whatever the plants need to grow well and produce fruit, i.e. tomatoes. But doesn't terroir or natural native soils impart nutrients and flavor that constructed soil and nutrient mixes do not provide?
It has been years since I've bought tomatoes in a grocery store. They're red, perfect-looking round objects that have no flavor at all. I simply do without until their normal season of fruiting...or use canned tomatoes which certainly taste like real tomatoes.
Is it really worthwhile to grow edible plants in such unnatural conditions, given it seems unlikely to me they can truly provide good quality nutrients and subtle flavors and tastes that an in-ground vegetable or fruit has? I grow ornamental plants of many kinds and they do well for the first two years or so but invariably when planted in native soil, they do much better.
Just curious.
I watched the whole videos from China, they were growing the bulbs outside, harvesting just prior and during flowering, then harvesting whole flowers, while sitting down, then someone else was pulling off the stamens.
It was not vertical farming. Basically vertical processing.
Our lettuce and basil beats organic farmed in flavor, useable lettuce (not one leaf is unusable) and the basil has better flavor. Easy to see who sells out at the farmers market and who doesn't. We sell our basil to a former 3 star chef, who now cooks pizza.
Like it or not, weather happens and outdoor crops fail all over the world. When we have rain, all the lettuce is bad, dirty, and cant be harvested. Lettuce wholesale costs tripled after the last rain. Ours was perfect.
There is a trade off between yield and flavor with tomatoes. There is only so much sugar to go around. Adjusting the EC of the fertilizer water will either increase water content (yield) or decrease water decrease (flavor).
My hobby goal might be to raise saffron in my aquaponics system.
I spent 9 months at Writtle College on sabbatical and we used to go to Saffron Upon Avon all the time!
I hope to learn from all of you, so excuse me if I am being rude.
Robin - here on a small, storm tossed island far North with 70 million people, compromises have to be made. My tomatoes taste better than the ones in the shops, but they're in a greenhouse and grow in peat free compost from the supermarket - best I can do. Anyone from Italy would not rate them.
<insert big argument about interplay of people and nature>
Suddenly wondering that if the Autumn sprouting flowering geophyte forcing for year around is possible, since most geophyte used for forcing should be frozen Spring sprouting ones which are naturally adapted to the frozen winter in the habitat. And if there were difference in the the flavor of fresh saffron and normal ones. (Or there should be 3 version cuisines (Fresh only, normal only, and both) combinations for the customer's experience.)
Quotehttps://www.researchgate.net/publication/283595994_Flower_formation_in_the_saffron_crocus_Crocus_sativus_L_The_role_of_temperature
The freshly formed replacement corms of saffron (Crocus sativus L.) had no chilling requirements, but sprouting only occurred after a period of after-ripening. Sprouting could be accelerated by a short curing at 30 °C. Shoot growth occurred at any temperature between 1 and 30 °C. The optimal temperature for shoot growth (23-25 °C) proved also optimal for flower initiation. No flower primordia were present in the resting buds. Flower organogenesis occurred during the early summer growth. The optimal temperature for flower emergence (17 °C) was markedly lower than for organogenesis.
Quotehttps://www.sciencedirect.com/science/article/abs/pii/S0304423804001104
The optimal temperature for flower formation was in the range from 23 to 27 °C, 23 °C temperature being marginally better. To ensure the formation of a maximum number of flowers, the incubation at these temperatures should exceed 50 days, although incubation longer than 150 days resulted in flower abortion. Flower emergence required the transfer of the corms from the conditions of flower formation to a markedly lower temperature (17 °C). Incubation of the corms after lifting at a higher temperature (30 °C), reduced flower initiation and caused the abortion of some of the initiated flowers. No flowers formed in corms incubated at 9 °C. A variable proportion (20–100%) of the corms forced directly at 17 °C without a previous incubation at 23–27 °C formed a single flower. The wide differences in the timing of the phenological stages in different locations we found in this study seemed related to the ambient temperature. Leaf withering was followed shortly by flower initiation, which occurred during late spring or early summer as the rising temperature reached 20 °C. A long hot summer delayed flower emergence which occurred in late autumn as the temperature fell to the range of 15–17 °C.
Quotehttps://www.actahort.org/books/850/850_12.htm
One month after the completion of flowering the plants were transplanted to the open field, and their CO2 assimilation rates were compared to that of plants coming from corms planted directly in the open. In plants grown at a constant temperature, this parameter, in the range 13-20°C, had no significant effect on the number of sprouts nor that of flowers formed per corm. Flowering occurred earlier at 17°C than at higher and lower temperatures. The flowers formed at 20°C had a wilt aspect. The size of the styles was directly related to temperature and therefore was highest at 20°C. In these plants, however, the styles were difficult to separate from the flower. Growing the plants at a 20/10°C term period hastened flowering and resulted in the formation of normal flowers, but also reduced style size. Growth in the chambers resulted in a 90% reduction of the maximum photosynthetic CO2 fixation as compared with plants grown in the open. This loss was recovered in part (about 50%) several weeks after transferring the plants to the open field.
I have only forced the usual run of spring flowering geophytes - narcissus, tulips, hyacinths, muscari, etc. Once potted up they require a chilling period for rooting. Refrigerator temperatures, that would be 38 to 42 degrees Fahrenheit - are considered suitable.
I remember one year, the New York Botanical Garden had a greenhouse display of Dutch bulbs. As with all their exhibitions it extends for a couple of months, determined by the powers that be rather than horticultural staff. The major problem was not coaxing the bulbs into early bloom but retarding them.
Obviously the Dutch have figured something out, as tulips as cut flowers may be had practically year round.
Judy
I think many of the cut flowers we see in markets are from Southern hemisphere locations like Columbia and Kenya
Judy - we often see on UK TV the preparations that go on for the Chelses flower show, there's a whole business of holding flowering bulbs back for it. Big fridges.
While living in a cabin near Fairbanks, Alaska, I got a catalog from a Dutch bulb company suggesting that bulbs could be "forced." I bought some, potted them, and put them under my bed to chill. At times they froze solid: no temperature control in that place. Nevertheless, they grew and flowered (under a grow-light), and I brought them to my university office to delight and amaze all. I especially remember the fragrance of Iris reticulata. That was when I started on the long road to my love of these plants.
In the mid 80's I was working for a large potted plant grower along the west coast. We were just getting into the potted Freesia boom.
We had weekly plantings of 5000 pots of 4" (3 corms each) and 2000 6" pots (5 or 6 corms each ).
It was a long time ago, so I am not sure what the season was, but some of the cultivars would pupate and not grow.
The challenge was not the lack of bulbs but how they responded throughout the seasons, especially after too long or short a chilling period.
Freesias want to grow in Winter. Here in the UK it is common to find "prepared" Freesias sold in Spring, Heat treated and designed to find the UK Summer, Winter like and grow and flower.
I also had luck sowing seed in early Spring and getting flowers in the same Summer.
I have plenty of Freesias which have reverted to type, growing in Winter, but never flowering.

The role of polyploidization in bulbous flowersJuly 2016NERINE Nerine bowdenii (2n = 2x = 22) is the main species of Nerine grown for flower production. The colour range is very limited. Therefore intergeneric crosses are produced using in vitro embryo rescue techniques. The intergeneric hybrid of Nerine bowdenii x Amaryllis belladonna was sterile therefore a fertile autotetraploid was produced (Van Tuyl et al 1992). Backcrosses of N. bowdenii x N. bowdenii x A. belladonna (Fig. 2) were produced and released to the growers.

It is interesting to point out that several polyploids previously analysed were considered to be autopolyploids, because they have similar basic bimodal karyotypes to those described in diploid species (Naranjo 1969; Naranjo and Andrada 1975).

Similarly, in the genus Hippeastrum, apart from diploids (2n = 2x = 22), there are triploids (2n = 3x = 33) in H. puniceum (from Guyana); tetraploids (2n = 4x = 44) in H. reginae, H. starkii and H. blossfeldiae; pentaploids (2n = 5x = 55) in H. scopulorum and H. cybister; and hexaploids (2n = 6x = 66) in H. puniceum (from Brazil) [65,75,76]. A number of Hippeastrum species are euploids, including H. forgeti (2n = 23) and H. iguazuanum (2n = 24), and aneuploids—H. blumenavia (2n = 20) [75,77,78].
Marks and Spencer sorry after displaying 'poisonous' daffodils next to food and under sign saying 'eat well'
"Daffodils are easy to mistake for a vegetable before they bloom but can be very harmful if eaten, with one expert comparing ingesting one to "swallowing a box of tiny needles". The flowers contain a toxic chemical called lycorine which can cause stomach cramps, nausea, diarrhoea and vomiting if consumed.
But, despite the potential for a dangerous mix-up, a display in one M&S store featured bunches of daffodils next to spring onions, with the plants and vegetables indistinguishable at first glance."

I was visiting a brother who had a pot full of very narrow, tubular, blue-green monocot leaves. I asked whether they were chives. He responded yes. I plucked one and began eating, finding no chive taste. At the same time he said "Or maybe those are those tiny little daffodils." I spit it out and had no ill effects. I again told my brother why labels are useful.

Cambridge moonflower: Rare bloom flowers again
A rare Amazonian cactus has bloomed, but its beauty was short-lived as it starts to die after just 12 hours.
The moonflower, or Strophocactus wittii, is part of the collection at Cambridge University Botanic Garden.
The plant is "very rare" in captivity and when it bloomed in February 2021, it was believed to be the first time one had ever flowered in the United Kingdom.
It bloomed again at about 17:00 GMT on Saturday.

Amorphophallus titanum is about to flower at the New York Botanical Garden.
"If you've never seen an Amorphophallus titanum, or the "corpse flower," now is the chance to visit The New York Botanical Garden (NYBG) where one is on display in the Enid A. Haupt Conservatory for the public to see, and eventually smell, when it blooms. The spectacular blooming flower gets its macabre nickname from the distinct odor, which some have described as similar to the smell of rotting meat, during its brief 24- to 36- hour bloom. Its smell serves a purpose, though, attracting pollinators that feed on dead animals. The final opening of the bloom is unpredictable but is expected to occur in the next week or two.

I wonder if it's the snapping of the water columns in the tiny xylem cells, considering the cut the stems or had them wilting. I recall in my plant physiology class 100 years ago that tiny microphones could pick those snaps up.
The breaking of these columns is non reversible and if its happening in lots of areas results in permanent wilting of that part.

Interesting comment. The story was in many places and they promoted it as a new discovery. But they did explain that the noise was of physical origin, like the way wood crackles when burnt.
BBC host Monty Don says year of weather extremes wreaked havoc on his garden
Monty admitted he is ready to replace citrus trees, cannas and dahlias with "truly hardy" plants that can withstand the havoc wreaked on his garden caused by Britain's changing climates.
"Watering expensive plants when animals and even people are going without is unacceptable, along with a level of winter protection that involves unsustainably expensive and immoral use of fuel, which directly contributes to climate change, thus exacerbating the problem."

Sheffield scientists call for ban on artificial grass
"Householders should receive a council tax discount if they garden sustainably", researchers have said.
Artificial grass and pesticides should also be banned to help protect the environment, according to a study by the University of Sheffield.
Professor Ross Cameron said gardens must be "full of plants to be beneficial to the local environment".
"Gardens account for a third of all our urban areas and are vital spaces in terms of keeping our buildings and city environments cool in summer, absorbing rain to avoid flash flooding and providing an important refuge for wildlife," he said.
"Many residents use artificial grass that kills much of the soil life underneath it, and when real plants are present, we wrongly assume we need to hit them with a cocktail of chemicals to keep them alive and free of pests."

Since many weeds that afflict our gardens are not native to our particular region, allowing them to crowd out other plants and spread to the vicinity is not what most people would consider a benefit to "nature." Last night, on the other hand, I sat through a polemic about choosing "native plants" (those recommended were not, in fact, native to our region, but to a nearby area with greater extremes of temperature and much less precipitation), and it was tiring. So, is your nature-lover happy with the shiny geranium? And does anybody know how to get rid of it? It's far too natural for me.
I frequently pull off the growing centre of numerous plants, but have not checked if the fleshy roots reqrow. Am I fooling myself by not digging it up? As it grows in cracks and crevices it would be quite a job to remove all the roots.

Of course, it totally depends on the plant. Dandelions are the worst, being near geophytes, sprouting from anywhere on the taproot. My local native bulbs have adapted to incidental browsing by having a weak connection at the top of the bulb (bulb reserves are much larger than the needs of a year's growth).
Persistence can help, keep at it so the plant never gets to photosynthesize. In some situations, targeted use of chemicals (natural or otherwise) may be a better solution than digging up a rocky area.
I was specifically referring to previous posting on Shiny Cranesbill, which does not have a taproot. Apologies.
A delightful, fun to use - and I think qualifies as organic or at least non-chemical method of weed destruction especially useful in killing weeds in pavement, gravel, etc - is the Flaming Dragon torch. It is an igniter wand that fits on a small workshop propane gas tank.
I have a Dragon but have not quite managed to develop the necessary techniques and in summer here it gets too dry to use in some areas.
However, one remedy for horsetail I do use (anti-chemical users - go hide) a brush killer undiluted in a small squeeze container, nitrile gloves on. I squirt a drop or two into the stem when I cut off the horsetail at ground level which I do immediately after cutting. So far, it's working well, but is incredibly time consuming so I only do it when I'm fed up with the things. Am trying this on cherry tree shoots this year but have doubts about effectiveness. We'll see.
But yes, thanks for the Dragon reminder which I can use in the driveway and the rock garden, very carefully.

This method of treatment for fresh cut hardwood works variously well. Rosaceae seems to be in the middle of the range of effectiveness...probably won't damage the root the sprout is coming off of. Heaths can be very sensitive. Poison oak/ivy is mildly sensitive. Oaks tend not to be very sensitive. Rhamnaceae...if you treat the new cut main stems it will usually kill the entire plant. Note that this is by practical application maintaining hiking trails, not garden practice.
Do Trees Really Support Each Other through a Network of Fungi?
Trees communicate and cooperate through a fungal web, according to a widespread idea. But not everyone is convinced
https://www.scientificamerican.com/article/do-trees-support-each-other-through-a-network-of-fungi/
For multiflora roses, Robert, here's a suitable, targeted method.
Get a number of those florist's tubes that look like a plastic test tube with a perforated rubber cap. Carefully add herbicide to tube and recap. Cut off a portion of the current season's growth, shove remaining flexible stem through cap into tube while making sure that the cut end is into the herbicide. Best to use a flexible branch and try to angle it so tube points down to ground rather than up in air. Herbicide will be absorbed into plant and down to roots.
Of course A) you need several (dare I say "multiple"?) units per shrub and B) you then have a dead shrub to dig and dispose of. Not so useful for thin stems such as Japanese honeysuck.
I did kill a rose that simply grew faster every time I tried to cut it back out of the way. What kind it was I have no idea but I cut it off at about three inches and painted every cut surface with undiluted Lily Miller Brush Killer. I so far have not had to repeat. It was not in the best location, afternoon shade and no water much of the year but it refused to quit blooming and was no deterrent to my dog who persists in barking at the pit bull he cannot see on the other side of the fence.
Next step, a row of Mahonia along that fence. I need to increase their fertilizer though or it may take longer than I'm on earth! Too bad cactus wouldn't grow there.

Kew Gardens: Endangered orchid species flowers in UK first
"A species of endangered orchid has flowered in the UK for the first time.
Dendrophylax lindenii, known as the Florida Ghost Orchid in the US and Cuba, has blossomed at the Royal Botanic Gardens, in Kew, south-west London.
It was flown into the UK from Chicago two weeks ago, with the bud displayed at Chelsea Flower Show.
Prof Mike Fay, senior research leader at RBG Kew, called the UK flowering a "positive conservation story".
While awaiting Thursday's bloom, he said: "This is a wonderful example of a successful collaborative conservation project, with several universities and botanic gardens in the USA working together for the greater good, highlighting the importance of orchid conservation around the world."
There are only about 1,500 ghost orchid plants left in south Florida and 500 in Cuba, Professor Fay said."

Deer and rabbits don't eat daffodils, nor do horses. That's above ground. Haven't noticed underground consumption which I assume would be voles.
During the Hunger Winter of WWII the Dutch ate tulip bulbs but never daffodils.
By now the story has been part of a BBC TV program "Countryfile" - it's only a chemical extracted from daffodils they feed to the cows.
Experiments are now under way. The gas comes out the front end, so measurements just require a gas mask.
An expert on the show said that it was an example of 'greenwashing' and that nothing short of a complete abandonment of live stock farming and reforestation of the land used would do.

Native shrubs and trees are especially important to birds. All of the smaller birds, even insectivorous ones, feed their young caterpillars. Native plants support large and diverse populations of caterpillars; ornamentals are more like supermarkets with bare shelves in the baby food isle. That being said, the world is full of interesting and wonderful plants that are a delight to have in one's garden. It's nice to have both native and non-native.
I'm sorry, I think this man is on another planet. His remark about nothing available to eat in the winter is nuts. This might possibly be true in some areas of the world but mostly not. Diversity yes, including natives, but ignoring natives that are adapted to the area where you live requires using up more resources than are needed or even essential, certainly more water.... And it requires garden practices that may be detrimental to the soil, i.e. pesticides and herbicides, among others.
Perhaps wild Britain is as bare as all the landscapes I see on the mystery programs I watch on TV. There are no trees or bushes at all - just short green stuff that is probably grass. The programs might all have been photographed up in Scotland, and maybe further south there are woodlands, but generally, it's a good thing that people plant gardens.

Alan Tictmarsh, is a secular saint, celebrity royalty and a winner of the RHS Victoria Medal of Honour. If you're in his pay bracket, you may encounter problems like wanting to turn the one acre field next to your large home into garden and being told by the local planners that a flower meadow would be more beneficial for the environment.
I suspect that is the problem, do-gooders saying what has to be done. They're sort of neo-gardeners.
Left to its own devices, re-wilding if you like, most of the UK would revert to woodland as it was before all the trees were cleared for fuel and ships. Some of the more exposed places would turn back to tough grass.
The current state is maintained by grazing sheep and other uses. Some of that is very pretty.

The reason for retaining edible landscape for wildlife should also be consider about introducing the concept such as novel food species for human and for wildlife.
For example, the native chestnut for food in the EU is Castanea sativa. Castanea mollissima and Castanea crenata (Japan) which are traditionally consumed by the East Asia people are novel food for the European people. And the concept should be also applied to the wildlife.

Nothing is cut and dried, nothing is simple.
In mild-wintered UK there is invertebrate food available in all except the worst weather. Many native and non-native plants produce food for wildlife, especailly woody species, especially in winter, although fruits and berries are foods of last resort for most birds as they can digest rather little of them, crows being a major and obvious exception.
As for rewilding - that name covers all manner of sins, from long grass to endless scrub, and almost nowhere in the UK is it unmanaged, using flooding, livestock, and/or mechanical methods to produce what somebody has arbitarily decided is what "should" be created.
The major "natural" modifiers of the UK landscape (in addition to man) are not even native - roe and fallow deer are introduced and there is increasing debate over whether red are introduced or not. Add in Reeve's muntjac, Chinese water, and sika (and the tiny managed herd of reindeer), plus rabbits - also introduced,. and you have a potentially, actual in some areas, huge grazing/browsing pressure.
As for trully natural habitat - where the soil, climate and aspect allow, it is now reckoned that the UK was something like what the New Forest currently is - a patchwork of open woodland.
Quote from: Diane Whitehead on July 30, 2023, 12:35:59 PM.......bare as all the landscapes I see on the mystery programs I watch on TV. There are no trees or bushes at all - just short green stuff that is probably grass.
That will be rather small areas, proportionally, where arable agriculture is profitable, and the green will be very largely cereals.
Very little grazing livestock in the UK is housed (or held in yards), except dairy and some (rather few) beef cattle for the worst of the winter weather when pasture would be puddled to death.
Huge areas that are grazed are rough, largely "unimproved" land - all of the moors in the SW, large areas of Wales and Scotland, the Peaks, the Lakes, Breckland - the list is almost endless.
You have a very mistaken impression of UK countryside - not all of it is like Lincolnshire (which is in large part, recalimed bog/marsh).
Lake District: New Zealand Pigmyweed spreads in Derwent catchment
"Conservationists are in a race against time to stop the spread of a highly invasive weed in the Lake District.
New Zealand Pigmyweed, which can spread from a tiny fragment, has taken hold throughout the Derwent catchment.
Swimmers, anglers and water sport enthusiasts are being asked to check, clean and dry their equipment to make sure it is free from weeds.
New Zealand Pigmyweed was recently found in Crummock Water and has been detected in Bassenthwaite Lake, Derwentwater and Loweswater.
Izzie Mullin, invasive species officer with WCRT, said: "It is incredibly adaptable and the smallest fragment measuring only 2cm can see it spread from one area to the next and it just grows into great dense mats on the water surface, completely outcompeting everything else."

Alan Titchmarsh hits out at Kew Gardens' plan to move botanical collection
"Alan Titchmarsh has said there is "no possible advantage" to Kew Gardens moving its historic botanical collection of dried specimens to a science park in Reading.
The proposed move has sparked anger among hundreds of scientists as the Herbarium, which dates from 1853, holds more than seven million specimens dating back to the 17th century, including a Galápagos fern collected by Charles Darwin and plants from the East India Company that launched the tea trade.
The Royal Botanic Gardens wants to relocate the plant library an hour away in the Thames Valley Science Park, a decision which botanists say will end careers, damage science and lead foreign countries to take back their collections."

He is principal investigator and director of a project called Realizing Increased Photosynthetic Efficiency (Ripe), which aims to genetically tweak plants to increase their yields by improving their ability to photosynthesise.
Prof Long and his team have used powerful computers to build a digital twin of the photosynthesis process. It can tweak that process in millions of ways.
From those millions of options the software can identify those that will make the biggest improvements."

Bananas contain a ton of potassium, which is one-third of fertiliser (along with nitrogen and phosphorus).
Potassium helps plants move nutrients and water between their cells. It is especially helpful for plants that flower - like peace lilies.

Popular garden plant BANNED after it turns out to be rapid-spreading invasive species

Quote from: David Pilling on December 09, 2023, 03:53:54 AMPopular garden plant BANNED after it turns out to be rapid-spreading invasive species
True to a point, apparently. Mentioned on GQT? Somewhere on R4 for sure.
Apparently someone checked the genes of a lot of different Gunnera in the UK and the great majority is a hybrid (details of the other partner, apart from true G. manicata, will be found online somewhere....). The non-mannicata species was already banned, but the principal with hybrid anything is that the hybrid assumes the position of the "worst case" parent.
It really is total nonsense. Whatever the plant is or is not in the UK, it is borderline hardy once you get away from warm coastal areas and the SW.
The plant will not have to be removed from UK gardens, but propagation and sale are now illegal, unless you can prove that the plant is not a hybrid, but genuine mannicata.
I have no idea if it is still there, but there was a Gunnera "forest" around the lake in Paignton Zoo - very, very impressive.
I recall many happy gardeners proudly showing off their Gunneras on BBC TV's Gardeners' World - enviro-criminals.
The story is in many of Saturday's UK newspapers. The Telegraph reckons it might be illegal to water the plant.
Shows the powers that be will change the rules when they want to.
Interesting that they use an English name "giant rhubarb." In Chile people harvest the stems and not only cook them (after peeling off the spiny outer layer) but also make a kind of liquor from them. Learned that when we happened on a group of locals getting the stems in a stream drainage. They were going to make booze.

I don't think that I have ever heard anyone with any kind of gardening interest or knowledge use the name in the UK - it is always called Gunnera.
Otherwise, I suppose it is an obvious common name to pick.
Quite why there is now this hue and cry about it is difficult to understand. Apart from Paignton Zoo, I have never seen anything but (very) modest clumps and in most of the UK it needs to be buried under plenty of straw each winter to protect againgst anything but very mild frosts.

Presumably G. tinctoria is already banned? No surprised that it hybridizes freely...they are pretty similar. It volunteers freely in Golden Gate Park, but it appears that gardeners weed it preferentially when seedling appear out of place. Otherwise quite marginal given the frost sensitivity and moisture requirements. There are some impressive stands in the park, often placed under tree ferns (or in some cases, over planted with tree ferns).
Quote from: Robert_Parks on December 10, 2023, 07:38:24 AMPresumably G. tinctoria is already banned?
Yes, banned a few years ago, hence my comment about worst case parent.
If you look at the "logic" of the whole thing, it is being banned because it is a hybrid of a banned species, no other reason. Maybe somewhere down in SW England, or somewhere very close to the coast in the W of Scotland (which actually has a very mild climate over large parts due to it getting "hit" by the Gulf Stream), there are large stands of the plant outside of gardens and parks, "feral"?
I have lived in S Devon and W Scotland, and saw no evidence of any problems.

Sounds like there is someone who has a hate on for tinctoria, and they are well connected or very persistent to drive this. Next they'll try for manicata. I think the next Gunneras in cultivation are quite a bit smaller.

Apparently world production is around 300 tonnes per annum, with Iran producing approaching 90% of it. The amount did surprise me - one hell of a lot of paella and/or pilau rice!

Saffron keeps better in the freezer. I also keep paprika and poppy seeds there. Now that I have a whole lot of Crocus sativus, apparently thriving in the veg garden, I will not worry so much about the purchased supply, however.

The first time that I bought whole bay leaves, I had no idea how many I was buying and that pack lasted something around 15-20 years and were prefectly OK when I used the last ones.
Quote from: janemcgary on December 28, 2023, 01:25:51 PMI have a whole lot of Crocus sativus, apparently thriving in the veg garden
Every few years I buy some Crocus sativus bulbs, but they never flower after the first year.
I am unsure how similar the growing conditions are but La Mancha and Iran may be a lot closer to each other in that respect than to Saffron Walden in the UK (which, long ago, was at the centre of a thriving saffron "industry", hence the name.)
Very dry all year, heavy alkaline soils would be where to start - S.W. is in East Anglia - my home area and it is not a desert only by virtue of the fact that the meagre rainfall is evenly spread over the entire year. Historically, huge tracts were used for sheep grazing as the land was fit for not much else - numerous towns and what are now villages made fortunes from the wool industry.
Lots of information should be online, but I used to live near Long Melford - a large village today - which has an enormous church, fit to be declared a small cathedral, and lots of other features, all paid for by the medieval wool trade.
In my former garden, Crocus sativus did well in a sandy, somewhat acidic raised bed, until the voles got to it. The current crop came to me after a researcher sent a large quantity of surplus corms to Mark Akimoff (Illahe nursery), which Mark shared with me. They were already in flower on arrival here, and I quickly stuck them in the raised bed where I grow vegetables in a mix of native clay soil, coarse sand, and organic compost, occasionally limed but still a bit acidic. They flowered well the second year and are now in leaf, which they'll be through winter. Some growers believe that plants from alkaline-soil habitats do well without high pH as long as they have adequate fertility. I don't add lime to my bulb soil mix, but I do use soluble complete fertilizer on the bulbs grown under cover, and a cool-season slow-release fertilizer on the open garden. The veg garden stays "chemical" free; it's really chemicals all the way down, of course, but nice to reassure friends who get the surplus zucchini.

I bought a £10 moisture sucking plant from B&M and it's worked wonders for damp and mould in my home
In fact there are quite a few clever houseplants that can suck moisture from the air and help prevent the build up of mould.
Eager to give one a try, I managed to find a snake plant - also known as a Sansevieria - at B&M, costing £10.
Other common house plants that can help banish mould include spider plants, orchids, Boston fern, English ivy, peace lily and palm plants.
https://www.manchestereveningnews.co.uk/whats-on/shopping/bought-10-moisture-sucking-plant-28630964
OK, admission first.......
Do I beleive any of the many and various claims about (house-) plants absorbing anything significant from the air?
No.
But I will work through any claims that people make, unless insanely daft before I even get that far.
The problem with trying to rationalise anything involving something like household conditions, including damp, is that there is never information about how and why things are damp, for how long, or when. There are countless imponderables.
However -
As a very general rule, the dew point inside an "average" UK house, will generally be about 1-2C higher than outdoors. There will be "stagnant pockets" of air that may creap higher (or even stay lower) in RH, but for mould to be a problem, not just a "dark mark" in a small corner of the room, we must be talking the bulk of any room.
Mould requires 70+% RH to really get going. At a room temperature of 20C, the air will contain something around 15g of water per cubic metre at that RH.
So let's say we need to be around 50% RH to be at least reasonably clear of mould, and the room is 20 cubic metres - quite small. So around 20 x 15 x (50/70) = 214g of water will have to be removed.
That assumes no more ingress of moisture.
Think about it.
I grow lots of Sansevieria, all indoors, I don't notice desication of anything.
I don't believe the claims - I have a dehumidifier running 24/7, every day I pour away 3 litres of water. Can a plant derive its water from the air and store it in its tissue - yes. Can it store 3 litres a day, no chance.
As a child adults would say that plants had to be removed from the room at night for safety - due to the CO₂ emitted. I one set up a CO₂ monitor, it is interesting how high CO₂ will get without ventilation (and that was a room without plants).
More folly, I just cannot understand how such waste of resources gets financed, for little more than garnishes.
The last section says it all.

I'd love to see some costings to understand the "logic". Especially at today's (or last year's) cost of electricity - so high, along with the price of gas, that many growers across Europe left their greenhouses cold and empty winter-spring 2022-2023.
Maybe the lighting is at a low level compared to producing anything but young plants/seedlings, which this sort of "farming" does. Maybe the plants have no time to etiolate?
Maybe the fast growth of seedlings allows fast enough turn-around of the growing space that output is high enough to offset the vast cost of running the growing room?
Interesting that the article lists a few companies that have gone bust in that line of business.
Climate change is turning the trees into gluttons
Sep27,2022
The study, recently published in the Journal Nature Communications, finds that elevated carbon dioxide levels in the atmosphere have increased wood volume – or the biomass – of forests in the United States.
This phenomenon is called carbon fertilization: An influx of carbon dioxide increases a plant's rate of photosynthesis, which combines energy from the sun, water, and nutrients from the ground and air to produce fuel for life and spurs plant growth.

The giants were first brought to the UK about 160 years ago, and a new study suggests they are growing at a similar rate to their US counterparts.
An estimated 500,000 trees are in the UK compared to 80,000 in California.

Of all plants, trees must be by far the most difficult to appreciate in photographs. There are a couple of this beech and one makes it look of no major consequence, the other is very different.
There are some fabulous beeches in the UK, not all of them huge. Some are very gnarled and stunted as a consequence of where they grow.

'Otherworldly' plant blooms for first time in decade
Birmingham Botanical Gardens said the Puya alpestris, from the Chilean Andes, began to flower in one of its glasshouses last week.
It is described as a "truly rare event" with visitors told they have just days to see the "exquisite" plant.
Staff, meanwhile, face a race against time to pollinate it by hand.
Puya alpestris is native to the mountainous regions of central and southern Chile and distantly related to the pineapple, the botanical garden said.
https://www.bbc.co.uk/news/articles/crgyw895qnko
I should lend them some hummingbirds - they pollinate Puyas in Chile.
On the BBC news at lunch time they had video showing a bloke up a ladder pollinating the puya and they said humming birds did it in habitat. It said that it spends years looking like a pile of dead vegetation before throwing up a huge flower spike.
It shouldn't look like dead vegetation. I grew this Puya for years in a big pot in a solarium, and it finally flowered. However, I got rid of it because I was tired of getting stabbed by its hundreds of fishhook-like marginal spines. In Chile, P. alpestris provides shelter for a rare species of chinchilla, and is encouraged to grow in the preserve dedicated to this little nocturnal mammal. The Chinchilla Reserve is also an excellent place to see many plants in flower around December, and interesting birds too. Puya species seem to be fairly easy to propagate from seed.

Extinct 'mountain jewel' plant returned to wild - in secret location
A plant that went extinct in the wild has been re-introduced to the UK mainland. We were there the moment pioneering horticulturist Robbie Blackhall-Miles returned it to its native soil.
...
I first met Robbie at his nursery for threatened plants - tucked away in a quiet part of North Wales.
He asks me to be careful how much we reveal - there is still a lucrative market for rare and special plants, often picked illegally, often fetching thousands of pounds.
...
The last time the rosy saxifrage was seen in the wild in the UK was in 1962, somewhere in the Cwm Idwal nature reserve in Eryri.
It is part of a family of mountain plants that thrived when northern Britain was frozen over during the Ice Age. When the glaciers melted, the saxifrages stayed, thriving in the mountain environment.
But their delicate appearance and beautiful flowers eventually made them a magnet for plant collectors - particularly Victorians who picked them for private collections.
The next part of the story has the quality of folklore - in 1962 a teacher and conservationist called Dick Roberts was in Cwm Idawl on a school trip.
He picked up a piece of a plant that had washed down a path, and put it in his pocket. Unsure of what it was, he took it home and grew it in his garden.
...
Some scientists talk about "plant blindness" - the idea that people don't see plants around them as important living things - instead, they're more like wallpaper in our natural environment, despite everything they do for our eco-systems and their role in producing medicine.

The pictures in the article are of white flowers. Why is it called "rosy"?
Quote from: Diane Whitehead on May 26, 2024, 07:37:02 AMWhy is it called "rosy"?
Always the difficult questions...
There's an interesting page:
https://www.plantlife.org.uk/plants-and-fungi/rosy-irish-saxifrage/
https://www.plantlife.org.uk/rosy-saxifrage-reintroduced-into-wales-after-62-years-extinct/
"Rosy or Irish Saxifrage Saxifraga rosacea subsp. rosacea"
They then call it 'Rosie'.
Perhaps the flowers are rose like - obviously rosy as in red not in operation here.
Lets go Latin
Rosacea (roe-ZAY-she-uh) is a common skin condition that causes flushing or long-term redness on your face.
Hmm.
"family Rosaceae), also known as whitehorn, maybush, or haw, is a fruit-bearing shrub consisting of bright red berries, white flowers, and bright green leaves. "
"Ner cast a clout till May is out"
Hawthorn (known as May) is notable for its white flowers.
Lets ask Gemini
why is Rosy Saxifrage called rosy
"The clue to the name of Rosy Saxifrage lies in the first word - "Rosy". This plant is named for the rose-colored flowers it produces. While Saxifrage itself is a genus that can have flowers in various colors, the Rosy Saxifrage has blooms that are a distinct pink or rose color. This characteristic feature is what earned it the descriptive name "Rosy Saxifrage.""
but the flowers in all the photos of Rosy Saxifrage are white
"As a language model, I'm not able to assist you with that."
Interestingly the above last answer is its final word, for a split second it displays something else...
Chat GPT
"Rosy Saxifrage, scientifically known as Saxifraga rosacea, likely gets its common name from the color of its flowers. The term "rosy" typically refers to a pink or rose-like hue, and many species of saxifrage have blossoms that exhibit such colors. This vivid and attractive floral coloration is a key feature that contributes to the plant's common name. Saxifrage itself is a diverse genus, and the specific epithet "rosacea" directly relates to the rose-like appearance, reinforcing why it is often referred to as Rosy Saxifrage."
but the flowers in all the photos of Rosy Saxifrage are white
"You are correct that the flowers of Rosy Saxifrage (Saxifraga rosacea) are predominantly white in most photographs. The name "rosy" might therefore be misleading if interpreted solely based on the flower color. There are a few possible reasons for this nomenclature:
Historical Naming: The name "rosy" might have historical or regional roots where the plant was first described or popularized. It's possible that there was some variation or subspecies with a slight pinkish hue that influenced the name.
Foliar or Stem Characteristics: In some cases, the term "rosy" might refer to other parts of the plant, such as a rosy tint to the stems or leaves, especially new growth or during certain times of the year.
Misinterpretation or Translation: Common names of plants often result from misinterpretations or translations over time. The "rosy" part of its name might have been derived from a characteristic that was either incorrectly observed or described.
Marketing and Appeal: Sometimes, common names are chosen for their appeal rather than strict botanical accuracy. The name "rosy" might simply make the plant more appealing or memorable to gardeners and plant enthusiasts."
Given that common names are not always scientifically accurate and can vary regionally, it's not unusual for there to be some discrepancy between the name and the actual characteristics of the plant.
I guess it's possible that all the pink-flowered ones were dug up over the centuries and only the unpopular white one was left to be discovered by Dick Roberts.
I wonder if pink ones are still growing in old gardens.
Quote from: Diane Whitehead on May 26, 2024, 08:52:18 AMI wonder if pink ones are still growing in old gardens.
Good point. Victorian gardeners are the villains of the story. There have been examples where gardeners stripped the wild of plants and none of them survived in captivity. On the other hand sometimes gardeners ensure the survival of species. Part of the BBC version is that they have reintroduced the wild plants, rather than obtaining them from Europe.
The wikipedia article answers everything:
"Saxifraga rosacea, or Irish saxifrage, is a herbaceous plant in the family Saxifragaceae. The epithet rosacea does not refer to its flowers which are white,[1] but to its radical sterile shoots which are often rosy.[2] Owing to this misleading epithet, the rosy-flowered Saxifraga × arendsii is sometimes misidentified as Saxifraga rosacea."

Tropical plants that were once transported on board the SS Great Britain have returned to the Bristol-based ship, for the first time in more than a century.

Volunteers needed to halt Himalayan Balsam menace
An appeal has been made for volunteers to help clear Himalayan Balsam from a site owned by the Woodland Trust.
The plant is considered an invasive species in the UK and has taken hold across the country - including at the Smithills Estate near Bolton.
It is hoped volunteers can help remove the balsam before the plant flowers in July and August and the seeds are scattered across the ground.
Himalayan Balsam was first imported to the UK by Victorian botanists in 1839, as a garden plant. It has no natural rivals and can reach a height of up to three metres.
It can quickly dominate ditches and streams because its seeds travel in the water, meaning riverbanks can quickly become infested.

Gardeners 'banned' from using vinegar to kill weeds for stark reason
Gardeners have been urged to take extreme care if they're using vinegar as a weedkiller in their garden this summer.
However, gardeners are being warned that vinegar can still be harmful to bees, which are a vital pollinator we're all trying to protect by avoiding lawn cutting and sewing wild flowers.
As one expert explains: "Vinegar is an astringent. If applied topically in a strong enough solution, it will dissolve the coating on the hairs of the trachea and the bees will drown"

The modern amateur is banned from accessing most chemicals, all that is left is vinegar, hence the books "a squillion and one uses for vinegar". However unlikely it is to kill woodworm or whatever one is advised to try it.

Gardeners urged to hang CDs in garden this July
You remember CDs - those shiny circular objects coded with music people used to buy before Spotify came along.
Now gardeners are saving their old Busted albums and putting them to use to protect their green spaces.
It might seem odd given their reputation, but birds are scared of CDs, and won't pinch your strawberries or peck at your raspberries if you line CDs along your raised beds.
https://www.express.co.uk/life-style/garden/1917976/gardeners-urged-hang-cds-garden-july
Over the years, what to hang in gardens/vegetable plots has changed.......
The most ancient of "guaranteed to work" were probably the foil cases/trays used for shop-bought pies and the like. The next idea was probably empty PET bottles, followed by PET bottles with some water in them (not much). The idea of using CDs has been around for ages (remember all those freebie AOL junk mail CDs?).
It is all fantasy. If it works at all, it doesn't for very long.
The other idea was to bury bottles so that their tops were just proud of the ground - the sound from the wind blowing across the tops would frighten/discourage various things.
I presume that people are pining for the gamekeepers' gibbet? Equally as effective.
Many of the fish and chip shops in Blackpool have flying outside the like of:
"Peregrine Pro Hawk Kites Professional bird deterrents that scare Seagulls and Pigeons away from rooftops
and gardens instantly. Kite on pole that takes a less than 5 minutes to install."
Seagulls being the second biggest predator of chips.
Kites I would have thought would work, but................
Maybe 6-8-10 years ago bird-shaped kites that had a very fast and random flight pattern - a very clever, but presumably simple design, as most clever things are - were very popular over crops that are (wood) pigeon magnets. I don't recall seeing one for quite some while, near certainly not since before C19, and perhaps they only persisted for a year, maybe two????
I haven't heard a gas gun for umpteen years either (although I seem to recall mutterings of banning them due to noise nuisance).
If anything is effective and cost-effective, it tends to hang around.

Botanists vote to remove racist reference from plants' scientific names
Offensive term to be replaced as first step towards more changes in unprecedented reform of nomenclature rules
Scientists have voted to eliminate the names of certain plants that are deemed to be racially offensive. The decision to remove a label that contains such a slur was taken last week after a gruelling six-day session attended by more than 100 researchers, as part of the International Botanical Congress, which officially opens on Sunday in Madrid.
The effect of the vote will be that all plants, fungi and algae names that contain the word caffra, which originates in insults made against Black people, will be replaced by the word affra to denote their African origins. More than 200 species will be affected, including the coast coral tree, which, from 2026, will be known as Erythrina affra instead of Erythrina caffra.

These aren't your typical roses and daffodils, though. Rather, these rare and exotic strains will only bloom under very specific circumstances - the right room temperature, say, or having its soil juiced up to a particular pH by crushing certain apple varieties into it. My favourite was the Wolfglove, which only bursts into life when you recreate specific sounds and wind speeds inside an old tower to mimic the environment of its mountainous home."
