Haworthia Cooperi var Truncata

Haworthia cooperi var. truncata is a stemless succulent that looks like a small grape cluster and makes small colonies up to 3 inches (7,5 cm) in diameter. It is a very quickly offsetting and smaller growing variety of Haworthia cooperi. The leaves are fleshy, soft, and glassy (almost transparent), 20 to 25 per rosette, round-tipped, and somewhat spherical with lovely blue-green translucent patterns. They become reddish when exposed to too much sun or not enough water.

The whitish flowers appear in spring to summer on simple stalks that can grow up to 12 inches (30 cm) long.
