These three natural (but wholly independent) groupings are combined here to fill out a list of some 65 taxa worthy of cultivation. The genus Ruschia proper should be separately treated, once it is sorted out. Of the 250 species in the genus, about 40 are horticulturally important. Sceletium attracts wide attention for its narcotic properties, the stunning Dactylopsis for its fleeting presence in collections (its one of the trickiest to cultivate). Bijlia sits perched like carved soapstone, and the fat fingers of Phyllobolus sprout from caudices.
