Cereus forbesii cv. Spiralis is a shrubby or treelike species dubiously thought of as a mutant Cereus forbesii. It is a (usually) trunkless cactus that forms numerous tall, ascending, columnar stems which branch at the base in a candelabra-like arrangement. Stems have a waxy bloom on the surface and reach a height of 2-4 metres (but can grow up to 5 m high or more), and are 10 to 12 cm in diameter. They have five to nine widely-spaced ribs. It blooms profusely during the summer. The flowers are white are followed by ornamental, red fruits. It is self-sterile and considered to be non-toxic however the spines are sharp so handle carefully.
How to Grow and Care
Light: It thrives best in light shade when young, then when they are mature, full sun is recommended, they need bright light all year round.
Soil: It grows well in a rich-organic, well-drained soil mix.
Water: Water regularly, during the growing season, but water sparingly when dormant (autumn and winter). Allow the top of the soil to slightly dry out before watering again.
Temperature: It prefers average room temperatures of around 16°C – 24°C / 60°F – 75°F. The temperature should not drop below 10°C.
Fertilizer: Fertilize once every 15 days with compounds containing nitrogen, phosphorus, and potassium or use a good cactus fertilizer.
Origin: Cultivar. Cereus forbesii is native to South America.
Propagation:
It can be easily propagated from cuttings in spring or by Seeds. Simply sever a branch and replant in moist, well-drained soil. It helps to allow the cut end dry out and harden before you replant it, this makes it easier for the new cactus to form roots.
