Blue Myrtle Cactus Plant Myrtillocactus geometrizans

The blue myrtle cactus plant, also known as Myrtillocactus geometrizans, is a unique and attractive succulent native to Mexico. It can reach up to 20 feet tall in the wild, but typically grows to around 6 feet in cultivation.

The blue myrtle cactus has a distinctive blue-green color and is covered in spines. It has a columnar shape with multiple branching stems and can develop a woody trunk over time. The plant produces small white or yellow flowers in the summer, followed by small, edible fruits that resemble blueberries.

The blue myrtle cactus prefers well-draining soil and full sun exposure. It is drought-tolerant and can survive extended periods of dryness, but it also benefits from occasional watering during the growing season. The plant is hardy to USDA zones 9-11, but can also be grown indoors in a bright, sunny location.

Propagation is usually done by taking stem cuttings, which can be rooted in well-draining soil. The blue myrtle cactus is relatively easy to care for and makes an excellent addition to desert-themed gardens or as a unique houseplant. However, caution should be taken when handling the plant due to its sharp spines.
