Haworthia semiviva

A small, highland Karoo Haworthia whose leaf tips dry to papery points, which gives it its name. It comes from the cold Roggeveld and Nuweveld escarpment at roughly 1,100 to 1,400 m, where it sees hot summers, frosty winter nights and very little rain. Grow it bright, dry and cool in winter, and water sparingly.

Where it grows wild

Nama Karoo and Succulent Karoo vegetation on the Roggeveld and Nuweveld mountains. Like its relatives it very likely sits half-buried among stones or in the shelter of small shrubs, which cuts the full Karoo sun; microhabitat detail was not found in the sources reached.

The weather sites sit at 1,140 to 1,390 m; the records themselves rarely carry an elevation.
