The south Western Cape contains rich succulents, but Haworthia is limited to a few species. It has its rainfall in winter, with the rainy season starting in April, building up to a peak in June-July, and ending in September. The summers are relatively dry. The high rainfall in the environs of Cape Town has no Haworthias discovered.
This area is the home of H. arachnoidea, H. maraisii, H. nortieri, H. reticulata, and T. pumila.
