Gasteria carinata var. carinata is found in coastal areas south of the Langeberg between Mossel Bay and Hermanus. The plants prefer to grow in the shade of bushes, but are also sometimes found growing in the open. Gasteria carinata var. carinata is quite variable and the plants from some areas make it difficult to distinguish between this species and similar species e.g. Gasteria brachyphylla var. brachyphylla.
