Osberg Ox-Tongue Overview

Gasteria koenii is an exciting recent discovery, confined to the southern foothills of the Groot Swartberg, near Calitzdorp. The mottled, sickle-shaped leaves are often long, narrow and drawn out and leathery, and grow in a central rosette. The leaves are brittle and those becoming detached, are very prolific, forming plantlets from the base. It is one of the few species of Gasteria flowering in autumn. The raceme is simple, with small, pendent, orange-red to pinkish flowers. ZA Distribution: Western Cape.
