These are dark grey-green, and lightly spotted (though juvenile plants sometimes have some rough tubercles).

This is a relatively wet region, and its habitat is typically cliff faces or rocky outcrops.

To the south, it gradually changes into Gasteria excelsa, becoming larger and solitary (non-clumping).

The Zulu people of KwaZulu-Natal call this species iqhomololo or impundu ("the invisible-maker") due its use as a medicine for camouflage during war.

Considered good luck, it is often planted on roof-tops, in the belief that it will divert lightning.
