''Bowiea'' is a bulbous genus of perennial, succulent plants which thrive in dry and desert regions of eastern and southern Africa. It is native to a region stretching from Kenya to Cape Province.〔(Kew World Checklist of Selected Plant Families )〕 The plants have many overlapping scales, which form a tight, pale green, spherical bulb that grows to 8 in (20 cm) above the soil, sending up a twining fresh-green branched stem with few linear deciduous leaves. Dormant in winter, when the outer scales and many of the scale tips dry to a paper-like state, the plants burst to growth in late spring or summer, producing one or more very fast-growing stems that needs to be supported by a trellis or stake. The stems are covered with many leafless side-branches that may fall off. The small greenish-white flowers appear in spring. The genus is named after the nineteenth-century British plant collector at Kew, James Bowie.〔Govaerts, R. (1996). World Checklist of Seed Plants 2(1, 2): 1-492.

Water rarely, except during the growing season. Propagate from seed. ==Species== One species is recognized, with two subspecies〔 *''Bowiea volubilis'' (climbing-onion, sea onion〔(Top 10 Ugly Plants )〕) * *''Bowiea volubilis'' subsp.
