Description
Plants grow in clumps of small rosettes of tiny, fleshy, light green leaves. As one of the soft green group of Haworthias it is frequently confused with its relatives (e.g. Haworthia cymbiformis, Haworthia mucronata and Haworthia marumiana).
A distinctive feature is the slight bristley "awn" on the margins of the leaves of most varieties. In some, the leaves terminate in a long bristle or thread. Its leaves are not recurved like the "retuse" Haworthias (e.g. Haworthia mirabilis or Haworthia retusa).
Another feature is that the leaves have transparent streaks around their tips. With some varieties, the entire leaf tip is transparent. In the wild, the sun is very bright, and the plant grows mostly buried by sand with only these transparent tips above the ground.
Distribution
The natural range of this species is in the Eastern Cape Province, South Africa. Here is occurs roughly between Port Elizabeth and East London in the east. This range closely matches that of its relative, Haworthia cymbiformis, and the two species interact, with H.cymboformis growing on the cliffs, and H.cooperi growing on the lowland plains. At certain points, the two species merge.
This is a summer rainfall region.
This is also a highly variable species - with several different varieties.
