Haworthia is a large genus of small succulent plants, mostly endemic to South Africa. Like Gasteria and Aloe, they are members of the family Asphodeloideae and they generally resemble miniature aloes, except in their flowers, which are characteristic in appearance. Horticulturally they are popular rockery garden and container plants. Typically they range from 4 cm to 20 cm high, depending on the species, though the inflorescences of some species may exceed 40 cm. Solitary or clump-forming most species have firm, tough leaves, usually dark green in colour, whereas others are softer and are window plants with translucent panels through which sunlight can reach internal photosynthetic tissues. Their flowers are small, white and very similar between species. But their leaves show wide variations even within one species. The charm of Haworthias is in their small size, ease of growth, and the almost infinite variation of their delightful leaves. Haworthias rarely require a pot larger than 10cm in diameter making them ideally suited for a bright windowsill. Perhaps the biggest problem you will encounter when growing Haworthias is that they tend to be addictive!

Haworthia glauca var. herrei is a South African indigenous succulent. It is endemic to the Eastern Cape Provinces Little Karoo where it is known to be found in only three locations, however, the full distribution is not yet known. This clump-forming species is caulescent (has above the ground stems) and the leaves have tubercles which cause their surfaces to be bumpy in texture. It has glaucous, incurved, grey-green leaves. In its natural habitat Haworthia glauca var. herrei is often found growing on rock slopes in full sun or under the weak protection of shrubs.
