Blue Candelabra Cactus
BeginnerMyrtillocactus geometrizans
A columnar cactus prized for powdery blue-green stems. Hardy and fast-growing, it is a standard grafting rootstock and a striking garden specimen.
About
The blue candelabra cactus (Myrtillocactus geometrizans) is a columnar cactus of arid northern-to-central Mexico (1000-2000 m elevation) and one of the best-known of all column cacti. It is admired for its beautiful blue-green, powdery (glaucous) skin and five-ribbed stems; in the wild it forms large stands up to about 5 m tall and wide, though it stays smaller in cultivation. With short, manageable spines plus fast, vigorous growth, it is an excellent and long-lasting grafting rootstock, ideal for carrying colorful grafts such as the moon cactus. Cultivation is easy: it likes full sun but appreciates part shade in peak summer. Water thoroughly when the soil dries in the growing season and sparingly in summer and winter, using free-draining soil. Mature plants bear cream flowers and edible sweet fruit.
