Carpet Weed (Cheiridopsis candidissima): A Silvery, Mat-Forming Mesemb from South Africa

Carpet Weed, Cheiridopsis candidissima, is a low-growing, mat-forming succulent from the Namaqualand region of South Africa. Its species name candidissima means "very white," referring to the dense, silvery-white waxy coating that covers its paired, finger-like leaves.

Seasonal Growth

This mesemb is a winter grower. In autumn, pairs of fleshy, cylindrical leaves emerge from a central sheath, forming a compact, silvery mound. The old leaf pair dries to a papery sheath that protects the new growth. In late winter to spring, it produces solitary, daisy-like yellow flowers that open at midday. By summer, the plant goes dormant, retracting into the soil.

Cultivation Challenges

Cheiridopsis requires a strict winter-wet, summer-dry cycle. Use a very gritty, mineral soil. Water only when leaves are fully turgid in winter; withhold water completely during summer dormancy. It needs intense light to maintain its compact, silvery form. It is a rewarding but demanding plant for enthusiasts of winter-growing mesembs.
