From Disporum on Wednesday 23rd of April 2025 05:14:46 PM PDT
Disporum sessile carpets low-elevation woods in Taiwan, Japan, Korea (Cheju and Ullung islands), and Russia (S Kurile Islands and S Sakhalin). It grows to 15-60 cm (6-24"). Pictured in Japan by Mari Kitama in photo 1. Photo 2 from Paige Woodward shows the rhizome and a shoot. She reports that her plants, of Japanese origin, are hardy to Zone 6, perhaps colder and bloom April to May 1-3 with creamy, tubular, green-mouthed bells at the tip of each stalk.
From Bongardia on Tuesday 22nd of April 2025 06:43:41 PM PDT
Bongardia chrysogonum (L.) Griseb. grows from 20-30 cm (8-12"). It grows from a large rounded tuber and has golden honey-scented flowers on branched, blue-green stems above spreading, pinnate, powdery grey-green leaves. Each leaflet has one or more indentations at the top and a gradually fading reddish-purple blotch. Balloon-like seed pods are produced before summer dormancy sets in. The flowers are hermaphrodite (have both male and female organs). This plant is native to rocky, montane slopes and cultivated fields where summers are dry and winters are spent under snow. It is in flower in May. It needs to be kept cool and dry during dormancy and prefers a warm sunny position in summer with well-drained soil as it dislikes excessive moisture year round. The tuber is edible and is either roasted, baked or boiled. Leaves are also edible, either used raw or cooked like sorrel. Photos from Paige Woodward.
From Brachycorythis on Monday 21st of April 2025 05:25:21 PM PDT
Brachycorythis macowaniana Rchb.f. is a South African species found in grassland or restio veld in the Southern Cape from Swellendam to the Eastern Cape. Growing from 10 to 23 cm, it has narrowly lanceolate leaves and small flowers in a dense raceme. Sepals are brownish, petals green and the lip cream to yellow, sometimes with a central green stripe. Flowering is November to December, after fire. Photos from the CD for the book Plants of the Klein Karoo courtesy of Jan and Anne Lise Schutte-Vlok.
From Dracontium on Sunday 20th of April 2025 05:33:25 PM PDT
Dracontium spruceanum (syn. Dracontium loretense) is distributed from Central America (Costa Rica) to Southern tropical America. It grows from a tuber that is approximately 15 cm in diameter. The stalk/scape has a spongy textured tissue 1 meter in length and a spathe 20-35 cm long, 3-6 cm wide and flower head (spadix) that is dark green, almost black. In Choco (Colombia) they call it the snake plant because of how the color of the scape/stalk is similar to a snake. They grate the bulb and it is used to dry up boils, and as an antidote for certain snakebites. Plant cultivated and photographed by Fabio F. Suarezmotta who collected it in the Lebrija River valley in the northern part of Santander Department (Colombia) in a pasture. He thinks that the periodic flooding of the Lebrija River carried the tuber from the wild down to where he collected it..
From Gelasine on Saturday 19th of April 2025 08:33:01 PM PDT
Gelasine elongata (Graham) Ravenna (syn. Gelasine azurea Herb.) is from southern Brazil and Uruguay and is found in grasslands to 100 meters. It has bright-blue or violet flowers that open in the morning and flowers in the summer. Although it is advised to treat this one like a Tigridia having it be hot and moist in summer and dryish in winter, I have found it can be grown on a Mediterranean cycle and given summer water. It stays evergreen for me treated this way and seems to do best in the ground, not a container. The first two photos by Bob Rutemoeller and the third from Bill Dijk. The fourth photo shows the pleated blades of a pot of seedlings in their second year grown by M. Gastil-Buhl.
From Arisaema Species One on Friday 18th of April 2025 06:43:31 PM PDT
Arisaema concinnum Schott is native from Himalaya to China (NW. Yunnan). It has very different coloured spathes, from green to purple, is 60/80 cm tall and has a radiate leaf. Photos by Giorgio Pozzi taken May 2006. The first photo shows the green form and the second photo the purple form. The next photo shows a backview of a spathe with an intermediate colour between the two, and last a closeup of a spathe (note the long spathe limb).
From Schizorhiza on Thursday 17th of April 2025 06:08:49 PM PDT
Schizorhiza neglecta (Goldblatt) Goldblatt & J.C.Manning, syn. Lapeirousia neglecta Goldblatt, is known to just three populations in Bainskloof, Jonkershoek and the Steenbras Mountains in the Southwestern Cape, South Africa, where it grows in rocky sandstone deprived soil at 400-1000 m in spots where additional moisture is available. It flowers in early summer (mid November to late January) following a fire the previous summer or autumn. Corms have corky layers and are ellipsoid with small flat bases producing several new corms in place of the parent corm at the end of the growing season. The 3-6 leaves are sword shaped to linear, slightly pleated with a prominent vein; the lower leaves are longest and inserted below ground level. The stem is branched with cormlets produced in the leaf axils above and below ground. Flowers are bilaterally symmetrical in an open panicle and either white with lower tepals with one or a pair of purple median spots (Jonkershoek population) or blue with darker blue to violet spear-shaped markings in the lower midline and often white-dotted in the center of the dark color (Bainskloof population). The first photo was taken by Rod Saunders of plants from the Bainskloof population. The second photo by M.Gastil-Buhl shows seeds acquired from Silverhill Seeds 46 days from sowing on a 1 mm grid. The third photo shows corms grown from those same seeds, on a 1 cm grid.
From Seemannia on Wednesday 16th of April 2025 08:20:17 PM PDT
Seemannia gymnostoma (Griseb.) Toursark. is native to southern Peru, Bolivia, and NW. Argentina. This Bolivian native is a tall (more than 1 m) summer growing rhizomatous winter dormant plant. It needs time to grow, but then flowers for a long time and has a relatively short dormancy. Photos taken by Johannes-Ulrich Urban of a cultivated plant grown under glass.
From Pseudomuscari on Tuesday 15th of April 2025 07:53:13 PM PDT
Pseudomuscari azureum (Fenzl) Garbari & Greuter syn. Muscari azureum Fenzl grows in alpine meadows in Turkey. It is 4 to 15 cm. with dense racemes of bright bell shaped blue flowers. First two photos by Mary Sue Ittner. Third photo shows a close-up of the inflorescence by Travis Owen.
From South African Oxalis Three on Monday 14th of April 2025 05:56:14 PM PDT
Oxalis dentata Jacq. is described in the field guide for Table Mountain National Park as a synonym of Oxalis livida and having a well developed, often branched hairless stem, trifoliate heart-shaped leaves that are purple below and 2-5 pale mauve flowers borne on an umbel. The illustration shows a mauve flower, but the leaves are very different from Oxalis livida leaves. In 2024 many sources list this species as being a synonym for Oxalis livida var altior. In 1950 Salter commented that there is a marked difference in the leaves and the root system of that species. Photos from iNaturalist of Oxalis dentata were taken by Tony Rebelo and vfbailey and shared under CC BY-SA and CC BY-NC licenses. These photos do not look at all like the photos of Oxalis livida var. altior on iNaturalist. So this is a puzzle. Some of the plants distributed under this name are obviously not this species. Christiaan van Schalkwyk received some that appear to be Oxalis uliginosa.
