Myrtillocactus geometrizans (Blue Candle)

Commonly cultivated around the world, Myrtillocactus geometrizans (Blue Candle) is a shrubby or tree-like branching cactus resembling a candelabra with age. The thick stems, up to 4 in. across (10 cm), are bluish-green, each with 5-8 ribs. Along the stems are areoles that bear 5-9 black radial and central spines. In summer, showy greenish-white flowers are followed by dark red or blue, very sweet, oblong fruits. Despite the large stature of this cactus, the flowers, 1 in. across (2.5 cm), and fruits, 1 in. across (2.5 cm), are rather small. Blue Candle starts blooming when it is about 2 ft. tall (60 cm). Easy to grow, Blue Candle is reported to be cold-hardy down to 25°F (-4°C) for short periods. Adding long-lasting beauty to the landscape, this eye-catching columnar cactus is planted worldwide in tropical climate gardens. Myrtillocactus geometrizans is commonly used as a rootstock for grafting cacti.
