Cotyledons are shrubby succulents with fleshy, fan-shaped, stalkless leaves arranged in opposite pairs. Each leaf of this plant has an undulating edge and a dense covering of fine, silvery white powder.
Although orange-yellow flowers may appear on older plants in summer, the plant is chiefly grown for its characteristic leaves. Mass several
plants together in a bowl on a low table for maximum effect.
Cotyledon orbiculata is slightly taller and has gray-green leaves edged with red, with just a little white mealy covering. Orange flowers appear in summer.
ORIGIN South Africa.
HEIGHT To 20in/50cm.
POTTING MIX Soil-based with coarse sand added in a ratio of 2:1 for good drainage, which is essential for this plant.
REPOTTING Move the plant into a pot one size larger each spring; when a 6-in/15-cm pot is reached, top-dress instead.
PROPAGATION Take 3-4-in/8-10-cm tip cuttings in spring.
KEEPING PLANTS Avoid handling the plant, since the white mealy covering will rub off. When the plant eventually becomes leggy, cut off the leafy top and reroot it.
The bare stem may then produce new growth, so It is worth caring for it for a while.
