About Velvet Cotyledon

Cotyledon velutina · also called Velvet Cotyledon · houseplant

Velvet Cotyledon is a compact South African succulent distinguished by its densely soft-hairy, velvety grey-green leaves that give the plant a tactile, almost felt-like texture. It produces cheerful orange-yellow tubular flowers on arching stems in summer. Well-suited to container culture in bright spots, it is drought-tolerant once established and easy to maintain.

Preferred mix: Gritty succulent compost

Watch for — Root rot from overwatering: Roots are sensitive to prolonged wet conditions. If the plant wilts but soil is moist, suspect root rot — unpot, trim rotten roots, dust with sulphur, and repot in fresh dry mix.

Why velvet cotyledon needs this mix

Velvet Cotyledon is an easy-going houseplant — it just wants a free-draining general mix that holds some moisture but never stays soggy.
