Myrtillocactus geometrizans – ‘Blue Myrtle’ (cactus)

Rated 0 out of 5
(be the first to review)




Myrtillocactus geometrizans is a medium to large sized slow growing cactus, native to central and northern Mexico. The fruit is an edible, dark purple berry 1–2 cm diameter, superficially resembling Vaccinium myrtillus (bilberry) fruit; both the botanical and common names derive from this resemblance (Wikipedia). The skin has a glaucous blue layer which is easily rubbed off, giving it an elegant appearance. 

A well utilised cactus within horticulture in its own right, for its stately and majestic appearance.  It is multi use, being a widely grown grafting stock and having tasty edible berries.

Care and Cultivation of Myrtillocactus geometrizans

Myrtillocactus geometrizans likes a well drained cacti mix (more inorganic than organic materials) and a full sun position. Apply fertiliser in spring and throughout the year, less to zero in winter/cold periods. Fairly tolerant and can be watered most of the year in all climates. Cold and drought hardy, frost tolerant.
