Trichodiadema bulbosum (African Bonsai) - This slow growing succulent plant is naturally a shrubby low growing groundcover with a tuberous base barely exposed and with stems rising 6 to 12 inches and spreading to several feet with small 1/4 to 1/2 inch long succulent gray-green leaves tipped with tufty bristles of soft white hairs. In cultivation this plant is usually elevated 4 to 8 inches to display its much branched swollen tuberous (napiform) roots and as such is often treated as a caudiciform succulent. From spring to late summer and sometimes on through fall appear the small flowers with bright violet-pink petals surrounding yellow-green stamens. Flowers open fully when grown in bright light or full sun. Plant in a well drained soil where it tolerates heat and full sun but looks best in part sun in hotter inland locations. Water occasionally to very little in spring and summer - with its tuberous roots can be forgiving of infrequent missed waterings, even when growing in a container. Hardy to around 25F or lower for short durations but prolonged subfreezing temperatures are liable to damage caudex if exposed. A very interesting succulent that is often seen is cactus and succulent shows. Grow plants for a few years with roots buried and then elevate the caudex and place in a nice bonsai container or ornamental pot to display the interesting roots. Trim off top growth only to keep growth tighter so it does not hide the caudex. Listed as from hilly locations of the eastern Cape Province and around Port Elizabeth in South Africa, though Heidi Hartmann in her treatment of it in the Illustrated Handbook of Succulent Plants: Aizoaceae had the distribution as "uncertain". It was described by the German botanist Martin Heinrich Gustav Schwantes in 1926. The genus name comes from Greek 'trix' meaning "hair" and 'diadema' meaning "crown" in reference to the bristle hairs that top each leaf and the specific epithet is in reference to the swollen roots.  The information displayed on this page is based on research conducted about this plant in our library and from reliable online sources. We also consider observations that we have made of it growing in the nursery's garden and in other gardens, as well how it has performed in our crops out in the nursery field. We will incorporate comments that we receive from others as well, and welcome hear from anyone who may have additional information, particularly if they have knowledge of cultural information we do not mention that would aid others in growing Trichodiadema bulbosum.
