Haworthia bolusii

A small, stemless rosette haworthia from the Karoo edge of the Eastern Cape, with soft, pale green, translucent-tipped leaves fringed with fine bristles that give the rosette a cobwebbed look. It grows among rocks and under shrubs on dry slopes, so it wants bright but not scorching light, a gritty mix, and a cool, drier winter.

Where it grows wild

Semi-arid karoo scrub and rocky outcrops, usually tucked into rock cracks or shaded by small shrubs, which keeps the rosettes out of full afternoon sun. Botanical detail specific to this species was thin in the sources opened; the microhabitat is inferred from the genus and the observation localities.

Observations run from near sea level to about 1500 m, most on the Karoo plateau around 800–1200 m. These are from record localities, not measured.
