From Zephyranthes on Tuesday 16th of December 2025 06:28:03 PM PST
Zephyranthes andina (R.E.Fr.) Traub (syn. Haylockia andina). The photos below were taken of plants grown by Hans Joschko. Plants start to grow in spring and flower just before the leaves appear. They were collected in Argentina in the north, near St. Victoria at an altitude of 3040 m not far away from the border of Bolivia.

From Mendocino Sonoma Coast Six on Monday 15th of December 2025 04:21:22 PM PST
Toxicoscordion fremontii formerly known and still listed in books as Zigadenus fremontii is a plant with white showy flowers in open panicles. It is found both near the coast and on the ridges. It can be seen flowering in abundance in areas that have been cleared by fire or otherwise the following spring. All species of Toxicoscordion are poisonous because of a toxic alkaloid they contain. There is a shorter form that may be this species or another that blooms earlier in the year than the more common robust form. Photos by Mary Sue Ittner of a plant blooming on the bluff at Salt Point State Park, and some growing on the ridge in Mendocino County.

Toxicoscordion sp. photos below were taken on The Sea Ranch in Northern California in January 2015 by Mary Sue Ittner and Bob Rutemoeller in a number of locations. This smaller, shorter species with thinner leaves grows in open grassy areas and blooms early in the flowering year. It doesn't quite fit any of the current descriptions for species. In the past we assumed these plants were Zigadenus fremontii var. minor, but in the change to Toxicoscordion and in the revised Jepson Manual this variety is no longer recognized.

From Hippeastrum Species One on Friday 12th of December 2025 05:10:12 PM PST
Hippeastrum correiense (Bury) Worsley is native to Brazil. Lee Poulsen wrote: "I got this from a large Japanese bulb company (Komoriya), and was told it was Hippeastrum coliense. I can't find a picture of it on the web anywhere, and when it bloomed, at first I didn't think it looked like the picture in the catalog. But then I realized that the front-on view looked the same and I just didn't know it had such a long trumpet and that this is as wide as it opens. The scape is about 2/3 of a meter tall." Photo taken March 2004 by Lee Poulsen.

From Eleutherine on Thursday 11th of December 2025 04:30:21 PM PST
Eleutherine bulbosa Miller (syn E. americana, E. anomala, E. longifolia, E. palmifolia, E. plicata, E. subaphylla). The typical flowers are formed on several rhipidia with secondary branching, open in the evening for about three hours and have no notable scent. Most plants in cultivation and all from Asia are sterile, while most fertile plants were found in Peru. If they set seed, the capsules are globose. Height range: 1-2 ft. Photos by Martin Bohnet of plants obtained from Thailand.

From South African Oxalis Eight on Wednesday 10th of December 2025 04:19:19 PM PST
Oxalis polyphylla Jacq. is a winter-growing species usually found on flats, light or heavy soils in the southern Cape (Malmesbury to Port Elizabeth). Growing to 20 cm with a bulb that is often gummy, it has rose, lilac or white flowers with a yellow tube and often darker margins, linear leaflets folded lengthwise and flowers March to June. The first two photos below were taken by Nhu Nguyen of plants from Telos Rare Bulbs. The last photo from the CD of the book Plants of the Klein Karoo courtesy of Jan and Anne Lise Schutte-Vlok.

Oxalis polyphylla var. heptaphylla is a winter growing, fall blooming South African species. Photo 1 was taken by Lyn Edwards. Photos 2-3 from Mary Sue Ittner and Bob Rutemoeller are offsets from plants originally collected by Michael Vassar as MV6396 at Vanrhynsdorp, Northern Cape, South Africa. It was described as: succulent thread-like leaves with up to 8 leaflets to a stem; corms often gummy; large satiny-lavender flowers. Photos 4-5 from Nhu Nguyen of the same clone, show a nice mass blooming in pot and the back of the petals when closed. The last photo shown from Mary Sue Ittner is of the bulbs on a 1 cm grid.

From Wachendorfia on Tuesday 9th of December 2025 04:59:19 PM PST
Wachendorfia brachyandra W.F.Barker is a short species with apricot yellow flowers found in sandy places between the Cape Peninsula and Saldanha in the winter rainfall area of South Africa. Height range: 20-65 cm. It differs from Wachendorfia paniculata, another short species, by having clustered stamens and style half as long as the tepals and flowers that wither shortly before midday. Photographed at Tienie Versveld reserve on August 24 2004 by John Grimshaw.

From Marah on Monday 8th of December 2025 05:44:49 PM PST
Marah macrocarpa (Greene) Greene is found on dry slopes from Santa Barbara, California south to Baja. The male flowers look like flat stars and the fruit is oblong and densely spiny. Previously known as Marah macrocarpus, this note in the Jepson Interchange for California Floristics explains the name change: "Correspondence 1 indicates that Marah is properly treated as feminine. [Therefore, spelling of epithet corrected to Marah macrocarpa (Greene) Greene, from Marah macrocarpus (Greene) Greene previously in this Index, 15 Feb 2011.]" Height range: 15-20 ft. Johannes-Ulrich Urban holds a fruit he found in southern California. Photo by Bob Rutemoeller.

The photos below by Nhu Nguyen shows the pods and very pretty shiny orange seeds and the fleshy roots below the new corms during the growing season. Notice the seed capsules are straw colored on the inside.
