Cereus forbesii 'Spiralis', also called Spiral Cereus, is a rare columnar cactus native to South America, particularly Argentina and Bolivia. This cactus belongs to the Cereus genus and grows naturally in dry, rocky terrain where it receives intense sunlight and well-draining soil. It is in high demand among cactus collectors.
Its dramatic twisted stem corkscrews upward in a tight, symmetrical spiral as it grows. Blue-green ribbed columns are lined with clusters of sharp spines and can reach impressive heights over time. The upright, columnar form of 'Spiralis' makes it a sculptural statement plant that occupies vertical space without spreading.
It is a night-blooming cactus that produces large white fragrant flowers opening after dark, typically in summer on mature plants. Blooms are fleeting and appear when nighttime temperatures drop consistently. A drop in temperature between day and night triggers flowering in this species.
Move it outside in summer into full sun to encourage blooming and growth. Rotate it occasionally for even, balanced spiral development. Choose a heavy pot for stability as deep roots develop over time. 'Spiralis' is drought-tolerant and serves as a dramatic indoor focal point or outdoor specimen in warm climates, and can be brought back indoors before autumn temperatures drop.
