[1][2] It is a small evergreen succulent plant, with hard, fleshy blue-green leaves that are covered in white tubercles.

Following phylogenetic studies, it has been shown that these four species in fact constitute a distinct out-group, separate from other haworthias.

[1][4] The epithet "minor" means "small" as it is not as large as its closest relatives, such as Tulista pumila.

The natural distribution of this species is in the far southern part of the Western Cape, South Africa.

It can be grown from seed, but it offsets and subdivides naturally so it can also be propagated simply by dividing the resulting clump.
