Gasteria glauca

Gasteria glauca ("Kouga Gasteria") is a succulent plant, native to the cliffs above the Kouga river, in the Eastern Cape, South Africa.

It has thick fleshy bluish ("glaucous") leaves which are distichous in young plants, but soon become a dense rosette. It is the distinctive grey-green colour of the leaves, which are often sharply pointed, which distinguishes it from the other gasterias.

It is most closely related to the species Gasteria ellaphieae, and also to Gasteria vlokii and Gasteria nitida. The flowers of all four species are also almost identical.
