This listing is for a popular cactus species which is both attractive and useful; Myrtillocactus geometrizans. Available here as live, well-rooted plants, cloned from our mothers in Spain.

Synonymous with Cereus geometrizans, Cereus pugioniferus, Myrtillocactus geometrizans var. pugionifera, Myrtillocactus grandiareolatus and Myrtillocactus pugioniferMyrtillocactus geometrizans is commonly known by names including ‘Bilberry Cactus’, ‘Blue Candle’, ‘Blue Myrtle’ and ‘Whortleberry Cactus’. Besides use for its ornamental qualities, geometrizans is well-known as a fast-growing (and quite forgiving) grafting stock. As well as the standard type, several cristate and monstrose cultivars are commonly available on the commercial market, including the very odd Japanese cultivar ‘Fukurokuryuzinboku’.

Native to central and northern Mexico, this is a shrubby-to-tree-like, branching species which can reach up to roughly four-and-a-half metres / fifteen feet tall. Stems of this delightfully blue-grey-green cactus grow up to approximately ten centimetres in diameter, featuring five or six ribs each. Note that it can take several years for plants in cultivation to begin branching. The flowers of this species grow to a diameter of approximately two-and-a-half centimetres, and are coloured a creamy white-to-whitish. These blooms generally begin to appear once the plant is at least sixty centimetres / two feet in height. Dark purple, edible fruit is up to two centimetres in diameter and is sold as a food in the plant’s native Mexico. It’s said to resemble the ‘Bilberry’ or ‘Whortleberry’ (Vaccinium myrtillus), contributing to both its informal and botanical names.

Provided you can give it enough light and a dry, warm and well-drained place in which to grow, this is an easy species to cultivate (whether you’re a beginner or an expert cactophile). Basically, it enjoys full sun and avoiding frost! Water only as the top few centimetres of soil dry out to the touch and fertilise two or three times a year for maximum growth.
