From Brodiaea Species Two on Saturday 20th of July 2024 06:13:54 PM PDT
Brodiaea matsonii R.E. Preston is an extremely rare species restricted to a single extended population along Sulphur Creek in Redding, Shasta County, California that is related to Brodiaea minor but has slightly smaller pale pink flowers. Published in 2011 after being identified, it grows from cracks and crevices in bedrock along an intermittent stream within foothill woodland. It usually flowers in early June on short stalks from 6 to 8 inches (10-25 cm) tall in a cluster of six to eight flowers. Photos from Dean Taylor shared here under a CC BY-SA 3.0 license.

From Mediterranean Ornithogalum on Friday 19th of July 2024 05:54:42 PM PDT
Ornithogalum umbellatum L. is a charming species spread all over the Mediterranean basin, but also reaching north to England and southern Sweden. In parts of middle Europe it is known to be a weedy species which is difficult to control due to its deep sitting bulbs. It has escaped cultivation and is spreading in the eastern half of the USA. Photos taken in habitat in Apulia by Angelo Porcelli.

From Isophysis on Thursday 18th of July 2024 06:35:59 PM PDT
Isophysis tasmanica is found in the mountains of western Tasmania growing in heathland on sandy soils. This is an alpine plant needing cool conditions. The flowers are yellow or dark red. Photos from iNaturalist taken by Kaely Kreger in Tasmania in December and shared under a CC BY-NC license.

From Cleistes on Tuesday 16th of July 2024 09:20:00 PM PDT
Cleistes bifaria is one of the most striking orchids within its range. It grows along the wetter margins of flatwoods, wet prairies, seepage slopes, and moist meadows. There was once only one species in the southern United States, but after relatively recent DNA analysis, it has been divided into two species. This species occurs near the coast from Mississippi through the panhandle of Florida north to North Carolina with additional populations in uplands of Tennessee, North Carolina, and West Virginia. It is a species adapted to a fire influenced ecology and suffers somewhat from the supression of natural burning in the southeast United States. The fifth picture shows how hard the foliage is to detect when not in flower and the sixth picture is of a nearly mature seed pod. Photos of wild plants in Bay and Gulf Counties, Florida.

From Salvia on Monday 15th of July 2024 06:01:06 PM PDT
Salvia patens is native to several states in central Mexico. It is a summer growing, winter dormant species where the plant dies down to just the tubers underground. It is an easy species to grow and plants can be obtained from various sources. This plant needs regular watering in summer, good well-drained soil, and good sun to thrive. In areas with little summer water and poor soils such as Mary Sue Ittner's Northern California, it did not thrive, but continues to grow in a large pot where water and soil can be controlled. In the winter, allow the soil to dry out a little but not bone-dry. Tubers will come into growth in the spring with flowers starting a month or so later. This plant can be grown from seeds and will bloom in the same season if treated properly. Photos 1-2 from Mary Sue Ittner and photos 3-4 from Nhu Nguyen.

From European And Mediterranean Romuleas on Sunday 14th of July 2024 05:14:17 PM PDT
Romulea sp. Photos below are of plants with a questionable identity. The first grown by Tony Goode shows a plant in cultivation in the UK thought to be Romulea bulbocodium. It seeds around gently in the garden and breeds true. The plants in the next photos were grown from seed exchanges and labeled Romulea linaresii and Romulea ramiflora. Angelo Porcelli suggested that they were Romulea ramiflora and that was how we labeled them. Photo #2 by Bob Rutemoeller. Photos #3-4 by Mary Sue Ittner show the flower being pollinated the first day it opened and the bracts and the markings on the back. A pbs list member from Southern California reports that this species became invasive in his garden. It has not been a problem in Northern California however. Photograph of corms on a 1 cm grid by M. Gastil-Buhl. There is a discussion on the PBS Forum in 2024 about these plants with the originator of the discussion suggesting that they are instead a form of Romulea bulbocodium as Romulea ramiflora is a much smaller plant. The discussion can be found here. The issue that originally moved these plants away from Romulea bulbocodium was that R. bulbocodium was described as having a sigma that overtops the anthers. In the plants shown below they are about the same height.

From Cautleya on Saturday 13th of July 2024 05:34:00 PM PDT
Cautleya spicata is a species that comes from the Himalaya, where it grows to three feet or so tall and bears red and orange flowers. Picture 1 shows the cultivar C. spicata 'Robusta' and is hardy in David Victor's garden down to temperatures of minus ten centigrade. Pictures 2 and 3 show the cultivar 'Crug Canary' grown by Martin Bohnet in container culture with dry, frost free hibernation.

From Juno Irises Three on Friday 12th of July 2024 06:52:27 PM PDT
Iris warleyensis Foster is a Juno from Central Asia. The pictured plant and several others of this species were grown from seed collected by Josef Halda in the mid-1990s and supplied without species identification. This is one of the most colorful Junos. The first photo by Jane McGary shows it flowering in a bulb frame in Oregon in March, kept dry in summer and covered against rain. The second photo by Oron Peri was taken in its habitat in Uzbekistan. Bulb photo by Peter Taggart.

From Moraea Species Seven on Thursday 11th of July 2024 07:08:55 PM PDT
Moraea pubiflora N.E.Br. is a summer-growing species native to Swaziland and the eastern Transvaal, where it grows in mountain grassland. The flowers are white to pale blue, and have unusually long, speckled inner tepals. The first two photos from iNaturalist were taken by Robert Archer in January in Mpumalanga and shared under a CC BY-NC license. The last photo by K Braun for the Swaziland National Trust Commission.
