From Prosartes on Saturday 18th of July 2026 05:03:25 PM PDT
Prosartes smithii (Hook.) Utech, Shinwari & Kawano, syn. Disporum smithii (Hook.) Piper, syn. Prosartes menziesii, syn. Uvularia smithii is found in moist shady forests near the coast from central California north to British Columbia. Growing from 20 to 90 cm, it has creamy white flowers that are larger than some of the other species, 1.5 to 2.5 cm long, that hang under the leaves and therefore are not easy to see followed by the pear shaped berries that eventually turns from green to large orange red. Stems and rounded to heart shaped leaves are usually hairless and stamens and style are enclosed within the perianth. Flowering occurs from March to June, fruiting from July to September. Photos 1 to 3 were taken by Bob Rutemoeller and Mary Hunter on the Mendocino Sonoma Coast. Photos below from Bob Rutemoeller and Mary Sue Ittner show the progression of the berries and the changes in color.

From Colchicum Species Two on Friday 17th of July 2026 08:31:32 PM PDT
Colchicum pannonicum Griseb. & Schenk is widely grown under this name, but in 2023 is now regarded as an excellent clonal selection of Colchicum autumnale sometimes known under the cultivar name 'Nancy Lindsay'. It has a distinctive purple color on the tube. Photos by Arnold Trachtenberg and John Lonsdale.

From Canarina on Thursday 16th of July 2026 05:14:43 PM PDT
Canarina eminii Asch. & Schweinf. is native to East Africa (Eastern Congo to Ethiopia, south to Malawi) where it grows in montane forest, riverine forest, and montane grassland. Height range: 6-8 ft. Photos from Dylan Hannon who writes "Canarina eminii is an epiphytic species that has grown well in the Los Angeles area (away from the coast). Here it is a winter grower like Canarina canariensis, though it starts growth earlier in the fall just as nights start to cool. Both are dormant and kept dry in summer."

From North American Fritillarias on Wednesday 15th of July 2026 06:03:05 PM PDT
Fritillaria biflora × Fritillaria purdyi hybrids. The illustrated plants are probably bee-made hybrids between F. biflora and F. purdyi, occurring among seedlings raised from garden-collected seeds of these two species. Possible F. purdyi × F. biflora (F. purdyi being the seed parent) is a very robust plant, flowering earlier than pure purdyi, with 10 flowers showing typical F. purdyi form and markings but with a green rather than white ground color. Possible F. biflora × F.purdyi, two of five flowering seedlings, are smaller at first flowering but otherwise similar to the first hybrid. All the hybrids have more glaucous leaves than F. biflora, a F. purdyi characteristic. Photos by Jane McGary.

From Lilium Seeds on Monday 13th of July 2026 05:21:05 PM PDT
Lilium seed
In viable seed an embryo is visible. This observation has led to the technique of "candling" seed, holding it up to a bright light to sort out the good from the bad. Very rarely seed can have more than one embryo. In some related species (see Fritillaria Germination) the embryo only develops after the seed is wet and exposed to low or high temperatures.
An alternative technique is 'winnowing', blowing over the seeds, the viable seeds are heavier because the endosperm around the embryo is thicker, the chaff is lighter and easily blown away. The following pictures were produced with a transparency scanner. In the first of Lilium regale seed, the seeds are oriented so that if they germinated the root would emerge downwards. This means it is possible to sow seed the right way up. Three seeds without embryos are visible. The remaining pictures are of Lilium amabile, Lilium formosanum, Lilium martagon, Lilium monadelphum and Lilium pyrenaicum seed. There is species variation in seed but it is small and there is variation dependent on how good a growing season has produced the seed.

Lilium seed pods. Successfully pollinated flowers will form seed pods and they will begin to swell. It is important they are left to ripen. This can be a problem because some species take a long time, and ripening pods can be attacked by caterpillars. When the pods turn brown and slight pressure causes them to start to split they can be picked. A lily seed pod contains three compartments each with two rows of seeds in. Typically there are one or two hundred seeds per pod. The first set of photos show a yellow trumpet lily seed pod.

From Eustephia on Sunday 12th of July 2026 05:11:58 PM PDT
Eustephia darwinii Vargas is from Peru near Cuzsco. It is a summer-growing plant, and requires a dryish winter to bloom. Height range: 5-10 ft. Photos 1-2 by Diana Chapman show plants that produce their flower stems in the fall. In the Bay Area, this plant blooms in July. Photos 3-6 were taken by Nhu Nguyen of plants grown by Uluwehi Knecht.

From Anticlea on Saturday 11th of July 2026 05:14:42 PM PDT
Anticlea elegans (Pursh) Rydberg (syn Zigadenus elegans). Inflorescences occur in loose racemes or panicles which can be denser at the terminal ends, with 10 to fifty upright cream colored flowers. A. elegans is native to a large range from Eastern Oregon in the West; north to Arkansas, southeast to Texas and east to Quebec and Iowa. It prefers moist and boggy areas and streamside habitats from grasslands to conifer forests. Height range: 30-60 cm.

From Disporum on Thursday 9th of July 2026 05:09:09 PM PDT
Disporum flavens Kitag. (syn. Disporum sessile ssp. flavens (Kitag.) H.S.Kim) is native to Korea and China and bears bright yellow terminal flowers on leafy stems shortly after emerging from dormancy in the spring. Height range: 2-3 ft. Photo taken April 2007 by Jay Yourch. In 2025 both Plants of the World Online and World Flora Online state the accepted name for this species is Disporum uniflorum Baker, but it is still listed as D. flavens elsewhere.
