The Spiral Cactus, scientifically named Cereus forbessii ‘Spiralis,’ is a distinctive plant that commences its growth as a straight cactus. However, once it reaches a height of approximately 10cm, its ridges start to spiral. In its natural habitat, it grows as a shrub, with numerous columns arranged in a chandelier-like pattern. This particular cactus lacks a trunk, producing numerous tall, columnar stems that are blue-green in color and spiral in shape. These stems, adorned with a waxy bloom on the surface, stand between 6 to 13 feet in height and measure 4 to 5 inches in diameter. They possess five to nine widely spaced ribs and are prolific bloomers. After pollination, the blossoms yield large purple fruits. Despite its sharp spines, this cactus is not poisonous.

Until the 20th century, most gardens and significant collections of cacti and succulents were under the ownership of the affluent. They became patrons of botanists in exchange for introducing new species to their gardens.

**Light:** Thrives best in bright light shade when young. Mature plants require full sun. Bright light is necessary throughout the year.

**Soil:** Flourishes in a rich, organic, well-drained soil mix.

**Water:** Regular watering during the growing season is recommended, but water sparingly in fall and winter when the plant is dormant. Allow the top of the soil to slightly dry out before watering again. The plant is suitable for xeriscaping.

**Temperature:** Prefers average room temperatures around 60°F – 75°F (16°C – 24°C). The temperature should not drop below 50°F (10°C).

**Fertilizer:** Fertilize twice a month with a complete fertilizer or use a specialized cactus fertilizer.
