Habitat

It occurs from near the coast to about 50 km inland, at altitudes up to 140 m. It is a constituent of Fynbos and grows in sandy soil in rock crevices which contain small deposits of very humus-rich soil derived from sandstone, mainly on east facing slopes. The annual rainfall, distributed throughout the year, is about 480 mm. H. venosa prefers a firm sandy soil with pH 6. From: Scott, CL. 1985. The genus Haworthia (Liliaceae): a taxonomic revision.
