Has anyone much experience with SCilla peruviana forcing. I have a mostly
white and blue colelction of the compact types with corymb heads that
flower reliably in February in California. For some reason this year I've
had poorer flowering results. Does anyone have references I could read on
this?

Narcissus Fly is not, thankfully, a beastie we need to concern ourselves
with here across our part of the pond but I would be interested to learn
if
anyone can tell me whether this insect has an infestation presence on
Lilium, etc.

I would also be grateful to know what this insect's scientific name is, it
surely must have one. Common names per se do not 'travel' well, perhaps we
know and experience it under a different name. Given that the genus
Narcissus is not indigenous to north America I wonder how it arrived there
should originate here in Europe, southern Europe to be more precise. Has
it
any relationship for over winter survival in terms low temperatures of
your
USDA's hardiness zones?

Dear Iain,

We have a wiki page devoted to this with information and photos that were
contributed from at least three members from across the pond so it
obviously is a problem in Ireland and the United Kingdom. Does anyone know
whether this fly is interested in bulbs from any other family besides
Amaryllidaceae?

Dear All,

Not having contributed for a long time in this list does not mean I
retired from bulbs..... on the contrary. I am dead-busy to at last get
the garden and house finished after some major changes, tired of
"pioneer works" I really do understand that this might also mean we have
a new President....
So "The Bulb Garden" came as a nice break and I must say thank you to
all the contributors. It is so well written and so full of unusual and
never-heard-before information. I have always been fond of Alstroemerias
but was not sucessful with them except a weedy A.aurea but this one
succumbed to the building activities in the garden....... I will for
sure come back to these plants once everything is settled here.
The article on Wave Hill Garden made me feel like hopping into a plane
to have a look myself...... America with its warmer summers for sure has
things to offer garden wise which I have never seen as yet......
Also very useful to know at last how to distinguish Cyclamen
hederifolium and C. graecum, honestly I always thought it is the same
species because I cannot see any difference between two flowering
plants. I grow both so next time I will watch out where exactly the
fruit stalk curls. Also very useful to read which Cyclamen grows on
which soil, this might explain some failure......
It is an interesting solution to that terrible space problem just to buy
twenty extra acres...... but can you guys let us all know how you solve
the TIME-problem?

Thank you all very much! Uli from Germany 35?C

Mary SUe wrote, Does anyone know

As far as I can see, it isn't. I have a large number of genera and
families
represented in my collection, and I have found bulb fly larvae only in
Narcissus, Galanthus, and Sternbergia. I now cover all the sternbergias
and
galanthus with screens or Reemay before the flies emerge but the narcissus
are so scattered around and so many of them that I haven't grouped and
covered them yet. I squeeze the bulbs hard when I lift them to test
whether
they have grubs -- the species I grow in the frames are all quite small so
this is effective though very disgusting.

This year spring was very cold for a long time, and the flies did not
emerge until about a month later than I have seen them before; they must
emerge in response to soil temperature (the larvae pupate in the soil, not
inside the bulbs)? Anyway, so far I have found very few infested narcissus
bulbs, and no pot with more than one bad one.

Chad,
"Oxalis rubra" is one of the most confused plants in an already confused
genus, Oxalis.
?
The plant you are probably asking about is probably best called?Oxalis
articulata ssp. rubra f. crassipes, although you will find this plant
listed under a dozen or?more different names. These might include Oxalis
rubra 'Alba', Oxalis rubra 'White', Oxalis crassipes, Oxalis crassipes
'White', Oxalis articulata 'Alba', Oxalis articulata 'White' and many
others.
?
Dr. Alicia Loureig's (deceased) paper in Phytologia?(1982) on Oxalis
Section Articulatae attempted to straighten out some of the confusion. It
is from this paper that the correct name of Oxalis articulata ssp. rubra
f. crassipes was established. In this paper she also?indicated that the
white?flowered version of this Oxalis was?described from a plant
cultivated?in Germany as from "South America".? Lourteig considers this
plant a white-flowered mutation that has been maintained only in
cultivation.? The stylar length can either be short or medium.
?
For a supplier of this plant, I think you'll find a few sources if you try
some of the synonyms above, especially using the term "crassipes" in your
search. Be aware that this white flowered version has somewhat smaller
flowers than the rose-pink plants that you are probably familiar with. I
also suggest that you hunt for one of the soft pink forms, which are
especially attractive.

Subject: [pbs] Oxalis rubra - white form ?

??? I was re-reading one of my older ('94) Pacific Horticulture
mags, an article on Oxalis had a picture of both white and pink flowered
O. rubra growing together. I like way the O. rubra behaves in the garden
- the large rhizomes are easy to find and it pretty much stay's put...
So I tried to locate a source for the white form on the web... No luck..
In fact I can't find any reference to rubra white or alba...

??? I suppose the white could have been another species - regnellii
comes to mind - anyone have ideas ?

Mary Sue:

I scanned through the article, which is very helpful. I seem to have
heard somewhere or read somewhere that vegetable oils can be used as a
spot spray on the foliage base to help with control...

As a matter of fact, I just found an article that refers to canola oil
and pyrethrins as a drench, "http://davesgarden.com/guides/bf/go/2436/",
but I know this is not the source I have in vague memory.

Anybody had any experience fighting the Narcissus fly organically?

I would like to get in touch with other Kniphofia collectors and
hybridizers
for exchange of plant material and cultivation experience.
I have a collection here in Denmark of around 100 species and hybrids.

If you are interested please contact me at tversted at email.dk

Dear Patrick,

We have discussed Scilla peruviana in the past a number of times as people
have written with the same question that you have. It has a reputation for
skipping seasons of bloom. This has been true in my garden, but apparently
is not true for everyone. I think in one spot of my garden it just got too
shady. Some people have suggested that it needs a dry period in summer to
do well. It gets that in my garden but still does not bloom every year.
Here was another suggestion from the past:
http://pacificbulbsociety.org/pbslist/old.php/…

By the way for all those of you who are new to our list and for those of
you who have forgotten the formula for searching the archives in Google is
found on the Pacific Bulb Society web site. It is:
+[pbs] [search terms] site:///lists.ibiblio.org

Google indexes all the posts from ibiblio lists. Unfortunately you can't
search from the archives for them, but you can search from Google. In the
Google box put in the formula above and substitute whatever you want to
find for "search terms". You may get previous and next posts in the list
of
messages you get, but you will also get the most relevant posts. In this
case you would put the following in the google search box if you wanted to
find previous posts about Scilla peruviana:

I remember somebody telling me, or writing, that he went out in his bulb
garden when they were emerging and whacked them with a tennis racquet. And
I think Steve Vinisky, a daffodil breeder, mentioned sending his children
out with butterfly nets. I had some luck last year using one of those
long-distance wasp sprays (not organic!) and nailing them on the wing.
They're easy to identify when flying because of the peculiar sound they
make, like giant mosquitoes. I got a couple this spring just by throwing
plastic pots at them. Very haphazard methods, all of these...I think a
spray at the base of the foliage, where they lay their eggs, is the best
idea and will try it next year.
