Cereus Forbesii cv. Spiralis | Spiral Cactus

Add one of the most extraordinary cacti to your collection with Cereus forbesii cv. Spiralis, commonly known as the Spiral Cactus. This highly sought-after ornamental cultivar is famous for its naturally twisting, corkscrew-shaped stems that create an eye-catching architectural display unlike almost any other cactus.

Native to South America, Cereus forbesii is a fast-growing columnar cactus, while the ‘Spiralis’ cultivar is prized for its distinctive spiral growth pattern. Its blue-green stems gradually twist as they mature, producing a dramatic sculptural form that makes it a favourite among collectors, interior designers, and succulent enthusiasts.

Whether displayed as a standalone specimen or incorporated into a larger cactus collection, the Spiral Cactus offers year-round visual interest. Mature plants can eventually develop multiple branches, creating an even more impressive spiral silhouette. Under ideal growing conditions, older specimens may also produce large, fragrant white flowers that bloom at night, followed by colourful ornamental fruits.

This unique cactus thrives in a fast-draining cactus and succulent soil mix containing mineral amendments such as horticultural pumice, lava rock, or crushed granite. It prefers full sun or very bright light and should be watered thoroughly only after the soil has dried completely. During winter, reduce watering to allow the plant to rest.

Ideal for modern homes, offices, greenhouses, conservatories, patios, balconies, and outdoor container displays during Canada’s warmer months, the Spiral Cactus combines low-maintenance care with exceptional ornamental appeal.
