Spiral Cactus 'Spiralis' (Cereus forbesii 'Spiralis') Plant - Cactuses & Succulents. A highly ornamental cactus with spiral stems, which is considered a natural mutation of the species forbesii - a view, however, disputed by some botanists. It is a slow-growing, medium-sized perennial variety with a bushy or tree-like form. Numerous upright stems of dark green colour grow from the base, with a candelabra-like arrangement. The stems are covered with waxy bloom and have 5 to 9 ribs. From the aeroles 2 to 5 spines emerge radially and 1 to 3 centrally. They are reddish in colour and the central spines are more robust than the radial ones. The Spiral Cactus 'Spiralis' blooms on summer nights, with large, white-pink flowers. The flowers are succeeded by red-coloured decorative fruits. The Spiral Cactus 'Spiralis' (Cereus forbesii 'Spiralis') is a very hardy xerophyte plant suitable for potting, gravel garden soil or rock gardens. It is used in both gardening and landscape architecture to create - among other things - dry landscape compositions (xeriscaping) or as a focal point plant because of its iconic presence.
► It is offered at a price determined by the particular characteristics of the cactus, such as the size of the pot, its height, and age. Large cacti are also available for sale (and planting) upon prior arrangement. In any case, the price or prices listed are indicative.
