Cactus Succulent Trees
A slow-growing, columnar cactus reaching up to 15m high in its natural habitat but generally growing up to around 1m tall in cultivation. Green stems to 30cm in diameter with 20-30 ribs and short white spines are covered in long, silky, silvery-white hairs. Nocturnal, funnel-shaped, yellowish-pink to red flowers are borne on mature plants in the wild but are unlikely to be produced by plants in cultivation
