Blue Myrtle Cactus
Blue myrtle cactus is a fun plant to observe.
It grows moderately fast and takes on different forms as it matures.
When young, its single stem grows straight up. Then, it will branch out to sport a fun, candelabra-like appearance, eventually becoming a giant shrub with numerous branches. Finally, once very mature, it will grow a central trunk to form a spectacular cactus tree.
One other rewarding aspect of keeping a Blue myrtle cactus is its fruits. Called "garambullos" by Mexicans and Guatemalans, these sweet fruits are also consumed by different Native American populations.
Botanical name: Myrtillocactus Geometrizans
Other names: Bilberry cactus, Blue candle cactus, Cereus geometrizans, Garambullo

Blue Myrtle Cactus Appearance
The blue myrtle cactus is a columnar cactus that got its nickname for its color and form.
The stems are bluish-green to deep green in color.
When young, the cactus grows vertically as a single stem, eventually branching out profusely to create a shrubby appearance. When very mature, the Blue myrtle cactus will develop a single trunk to form a tree.
Can grow to 10-15 feet tall and twice as wide.
Thick stems with 5-9 ribs and sharp spines. The ribs form an interesting geometric pattern, hence the word "geometrizes" in its botanical name.
The smooth, waxy surface below the spines. The bumps and waxy surface help to save moisture within the plant.
Large and showy cream-colored flowers when in bloom.
Followed by edible, dark, oval-shaped fruits called "garambullos" in Spanish.
