From Toxicoscordion on Sunday 18th of October 2026 05:32:09 PM PDT
Toxicoscordion fremontii (Torrey) Rydberg (syn. Zigadenus fremontii (Torr.) Torr. ex S.Watson) is found in the California Floristic Province from southern Oregon south to Baja California. It grows in variable habitats, both coastal and inland, in grassland chaparral and mixed evergreen forests. It flowers from February to June. It is very variable in height with white showy flowers in open panicles. Height range: 40-90 cm. Photos 1 from Mary Sue Ittner and 2 Bob Rutemoeller give you an idea of how floriferous it can be and show a close-up of the flowers. Photo 3 shows the bulb on a 1 cm grid. Photos 4 & 5 from Mary Sue Ittner are habitat shots taken in northern California. Photo 4 shows a plant growing near the Pacific Ocean in Salt Point State Park on the Mendocino Sonoma Coast and photo 5 was taken in Mendocino County where they grow on the ridge in mixed evergreen forests.

From Babiana Four on Saturday 17th of October 2026 05:31:16 PM PDT
Babiana scariosa G.J.Lewis grows on dry sandstone or clay in fynbos or karroid scrub from the Bokkeveld Mountains in the northwest Cape to the western Little Karoo. It flowers from August to September. It has linear-lanceolate, pleated leaves and blue to mauve flowers with white to pale yellow markings on the lower tepals. The lower tepals are clawed and united. Height range: 10-40 cm. The first photo was taken by Alan Horstmann and the second by Cameron McMaster in the Hex River Pass.

From Tritonia Two on Friday 16th of October 2026 05:05:48 PM PDT
Tritonia crocata (L.) Ker Gawl. is one of the most commonly grown species and one that has been hybridized as well. It has orange to reddish flowers, but without prominent veins. Height: 25-50 cm. It blooms in late spring. It grows on stony clay slopes in the renosterveld in the southern Cape. The first three photos by Bob Rutemoeller and Mary Sue Ittner of California grown plants including a nice companion planting in the garden with Iris douglasiana. The last two photos were taken by Alan Horstmann.

Tritonia crocata has naturalized in the California garden of Michael Mace, where it grows at the base of a Japanese maple tree in part shade. The bulbs grow in a layer of mulch on top of the clay subsoil, and are dry in summer. The dead leaves are from Moraea aristata, which has also naturalized in the same spot. The second photo shows a white form that cropped up in the patch.

From Raphionacme on Thursday 15th of October 2026 05:29:39 PM PDT
Raphionacme velutina Schltr., syn. Raphionacme burkei N.E.Br., is native to Angola and Zimbabwe. It has a large mostly spherical and more or less flattened tuber growing above ground. The deciduous stems are vine-like and the flowers pale green star-shaped with a purple center. This species flowers in summer. The photo below was taken by Maria Botwright who asked for help in identifying it. She described it: "I picked up a plant which looks like a flattened football. It has a smooth appearance and is light beige in colour. From its center a yearly stem comes out. It bears parallel leaves along the stem, which is approx 1 foot 6 inches and bears small, insignificant, bell shaped white flowers."

From Doryanthes on Wednesday 14th of October 2026 05:28:41 PM PDT
Doryanthes palmeri W.Bull is a species from Queensland and New South Wales known as Spear Lily. Photos #1-3 below were taken by Alberto Grossi in northwest Italy, near the Italian Riviera. Height range: 6-10 ft. The first two pictures of an inflorescence and open flower were photographed at the Botanical Gardens Hanbury at La Mortola, and the third is of a whole plant with fruits at Villa Ormond, San Remo. Photos #4-5 were contributed by the UC Botanical Garden. Photo 6 was taken by Nhu Nguyen at the UC Botanical Garden.

From Pyrolirion on Tuesday 13th of October 2026 05:03:40 PM PDT
Pyrolirion albicans Herb. was named by Herbert in 1837 for a Peruvian species illustrated and described in 1725. It is the accepted name in Plants of the World Online. Mobot's Tropicos database list these accepted names for this species, Cooperia albicans (Herb.) Sprague and Zephyranthes albicans (Herb.) Baker. Further confusing the issue of what to call this plant, Ravenna renamed it Leucothauma albicans in 2009. We are choosing to list it on the wiki under Pyrolirion albicans. Height range: 25-38 cm. Photos by Alessandro Marinello.

Raven, Oenothera subacaulis (Pursh) Garrett, is found in wet meadows at 450 to 2600 m in these western states: Washington, Montana, Wyoming, Colorado, Utah, Nevada, and California. Leaves are in a rosette, lanceolate to narrowly elliptic, usually entire, but sometimes irregularly pinnately-lobed and glabrous. The fruit is 4-angled, barely swollen by seeds, leathery. It flowers May to July. Leaf length: to about 22 cm.

From Mandirola on Sunday 11th of October 2026 05:26:19 PM PDT
Mandirola ichthyostoma (Gardner) Seem. ex Hanst. is the most common species of the genus in cultivation. The species epithet translates to "fish's mouth". It prefers to grow in moist conditions, and some people grow the plants with part of the root system submerged in a tray of water. It produces tiny little scaly rhizomes. Height range: 15-20 cm. The photos below were taken by Nhu Nguyen of plants grown by a member of the San Francisco Gesneriad Society.

From Lachenalia Species Six on Saturday 10th of October 2026 05:25:25 PM PDT
Lachenalia suaveolens (W.F.Barker) G.D.Duncan, syn. Lachenalia elegans var. suaveolens, is distributed from the Bokkeveld Plateau to the southern Tanqua Karoo. Growing from 16 to 40 cm with 1 or 2 lanceolate leaves, it has spreading light to deep pink to purple flowers without pedicels with dark maroon markings and recurved apices on the lower tepals with narrow, bright white margins. It flowers September to October; flowers have a carnation scent. It is allied to Lachenalia membranacea, but that species has light yellow to greenish-yellow or rarely light blue outer tepals and light greenish-yellow or white inner tepals and spreading leaves. Since Lachenalia elegans has been split into four different species, we cannot be sure, but believe that these photos are this species. The first two photos by Bob Rutemoeller and Alan Horstmann. Photos 3-5 were taken by Mary Sue Ittner near Nieuwoudtville September 2006. The last photo was taken by Cameron McMaster September 2011.
