Dear Rhoda, Thanks for your introduction to Ledebouria. I've attempted several crosses this Spring with Ledebouria: L. galpinii X L. socialis , L. rupestris X L. socialis, and L. crispa X L. socialis. With each I've also tried the reverse cross. Galpinii X socialis yielded two seed, and there is now one seedlings. It remains to be seen if it is a hybrid. Rupestris X socialis yielded 4 seeds, and these have just been planted. Of about 6 differing clones of L. socialis I grow only a couple seem to be fertile, even when intercrossed. Ledebouria rupestris displays a valuable characteristic in having very long lasting flowers starting a grayed purple and aging green, but with an attractive from. I see you have added a new Ledebouria image to the Wiki, L. species growing from a hole in a vertical rock face. Eastern Cape. Hope you give us some idea of scale. Look forward to additional images. Thanks for all the time and effort.

The unpublished revision done in 1993 by S. Venter is the most recent, but it is still not easy to use especially when the bulbs are not in flower. In October 2002 a vegetative key was published by A. Hankey (following Venter's revision) which is more user-friendly. > > Ledebouria species are from a few cms to about 30 cms tall, usually having interesting or decorative leaves which can make appealing pot subjects, especially the dwarf species. Their flowers are arranged on a floppy spike mostly appearing in early spring before the grass is up. The individual flowers are not large or showy, but when examined closely they are exquisite with various colourings of mauve, purple and pink (sometimes almost luminous) on the stamens and pedicels. They usually like to grow amongst rocks or in grassveld. They go dormant in the dry winters, and can tolerate a degree or two of frost. In the montane grassland species, they would get a bit of winter moisture from mist or the occasional light shower/snowfall. > > The seeds of most of the summer rainfall species are usually ripe by early summer and ready to germinate immediately with no fuss. I have found a clone or single plants do not set seed. They seem to need cross-pollination to produce seeds. Does anyone know how easily they would hybridise? > > Hankey divides the South African species into three Sections. > > In Section A with leaves erect (majority on an axis closer to 90 than 45 degrees), there are eight species, including: > L. viscosa which has sand particles sticking to the leaves. > L. dolomitica and L. cooperi which may both sometimes have more floppy than upright leaves and are therefore also listed in Section C. > L. sandersonii can be very confusing with very variable leaves, and is listed in all three Sections! > > In Section B with leaves adpressed to the soil surface, there are seven species, including: > L. galpinii, a delightful miniature with purplish-green textured leaves, and a beautiful little cluster of pink flowers in early spring. > L. ovatifolia, which occurs to tropical Africa and Sri Lanka. > L. ovalifolia (confusing with the previous name!!) which I would include in Section C because my plants have semi-upright leaves, definitlely not pressed to the ground. Could it be a hybrid? This one is from the winter rainfall region with a summer dormancy, or evergreen in my experience growing it here in Napier (the Overberg region of the Western Cape). > > > In Section C with leaves variously spreading but not erect or adpressed, there are 25 species, including: > L. hypoxidioides, so called because of the likeness to a Hypoxis with hairy (on both sides) leaves. > L. rupestris, a dwarf species with interestingly textured leaves. > L. socialis, a small species with the bulb exposed and very attractive silvery mottled leaves. > L. crispa, a dwarf species with a most attractive crisped leaf margin. My single bulb has multiplied vegetatively into a decorative clump. Alas, no seeds. > L. floribunda, a large species, usually with beautifully spotted leaves. The traditional healers in the Eastern Cape use this bulb. > L. revoluta, a medium size species, with dull or dark spots on the leaves. It occurs from Port Elizabeth into eastern Africa and as far as India. There are many around Stutterheim in the Eastern Cape. Apparently the bulbs are edible. > > I hope to post some pics to the wiki tomorrow. > > References and some further reading: > > Craib, C. 1998. HERBERTIA Vol. 53: 49-53. > Craib, C. and A.
