Oscularia cedarbergensis

A shrubby ice plant from the Cederberg region of the Western Cape, growing among sandstone rocks in a winter-rainfall climate. Give it full sun, a free-draining gritty mix, water mainly in the cool season and keep it dry and airy through hot summers.

Sites range from about 300 to 1,000 m; few records carry an elevation.
