Gasteria croucheri is a solitary or cluster-forming plant, up to 400 mm high, with ascending, spreading leaves. It sometimes forms small clusters of up to 8 individuals or more. The leaves occur in opposite rows or rosettes, are tapering, strap-shaped, 200-360 mm long, and 30-100 mm broad at the base, with a smooth but mottled skin (epidermis), the top rounded with a short, pointed mucro. The leaves in young plants are always opposite (distichous), some are rough (tuberculate) and look quite different to the smooth adult leaves.
