Cotyledon woodii is a much-branched, succulent shrub, up to 1.2 m tall. Erect branches are succulent and green initially, slightly woody with maturity. Light grey-green leaves are flat, hairless and obovate. Solitary, orange to red flowers are presented on a terminal, short, inflorescence stalk, from December to April, with sporadic flowering year round.
Cotyledons can be divided into two groups. One group consists of evergreen plants with a summer growing period. The other group comprises deciduous plants, splendidly magnificent with large, solid, fleshy stems. The second group grows during the winter and sheds its leaves during the summer.
Cotyledons require a free-draining soil mix and plenty of sunlight. They tolerate cool, frost-free conditions during the winter if kept dry. Some require pruning to maintain an attractive shape.
Cotyledons should be kept in a sunny position. Follow general succulent watering procedures. Be careful of overwatering when Cotyledons are deciduous.
