Mostly from the Eastern Cape of South Africa, these perennials grow from a large bulb that forms several new offsets a year as it matures. Allow to clump, or dig and divide every 2-3 years. These surprisingly hardy plants relish rich, moist loam with no standing water in winter while they are dormant, and plenty of sun and moisture during summer growth and bloom. Protect with a thick gravel mulch in cold areas, and be patient in spring- they may be slow to wake.
