Many species of this attractive succulent are available to the greenhouse gardener. Foliage may be arrow-shaped, notched, or curled; flowers yellowish green, creamy-white, coral-pink to scarlet-red. Sow seeds in March for flowering plants by Christmas. Shade from 5 p.m. to 7 a.m. from August 15th until October. Transplant to 2/2-, then to 4-inch pots in mix of two parts garden loam, one part peatmoss. Provide good drainage, keep moderately moist. Occasional dilute solutions of liquid fertilizer promote stocky compact growth.
Mealy bugs are a real problem. Inspect frequently for this pest, treat immediately with swabs dipped in alcohol. If you cannot control the infestation, destroy the plant. Do not use DDT; it may seriously injure or kill the plant.
