Description: Very tall but relatively thin rarely if ever branching columnar cactus, but sometime it branch at the base producing a candelabra shape..
Stems: Columns up to 15 cm in diameter but up to 9 m or more tall. Green, grey green to glaucous green.
Central spines: Absent.
Radial spines: Neat cactus with generally 1 to maybe 3 (or five in young specimen) spines per areole. They are blackish to reddish-brown. As ages, spines tend to fall out and plant somewhat resembles a large Euphorbia candelabra.
Flowers: Nocturnal from the sides near the apex, and ruffled pink-red with a pale yellow centre. Plants starts flowering at about 120 cm in height.

Cultivation and Propagation: They are of easy culture and can grow 15-20 cm a year. They are cold intolerant. Make sure they are not exposed to freezing temperatures ( Hardy to -2°C) or they may die. They need a well drained soil mix. Water regularly in summer but allow to dry fully before watering again. During the winter months they should be rather kept dry. Since they are rapid growers, they need plenty of space for their roots. Repotting should be done every other year, or when the plant has outgrown its pot. Sun Exposure: Light shade when young, full sun later.
Propagation: From cuttings in spring (let them dry till the ends callous well). Then replant them in fresh cactus soil that is ever so slightly moist, and keep it that way till they root), or by Seeds (Seeds should be sown in a well-drained soil mix. Surface sowing is the best; seeds germinate in 14-28 days at 25° C .
