Browningia hertlingiana, or Azureocereus hertlingianus, commonly called blue cereus, is a columnar species of cactus belonging to the Cactaceae family. B. hertlingiana is natively found in South America growing on dry high altitude slopes in Peru. Younger plants of this species exhibit a vibrant blue epidermis that gives this species its common name.  Mature plants reach up to 20 feet tall and can reach 13 feet wide from branching although it rarely does. The central spines are slightly more prominent than the radial although all are robust with yellow to yellowish gray color and brown tips. Flowers typically emerge in the summer months and only bloom at night. The flowers are curved and tube-like with a dark purplish color and have a 2 inch diameter. Blue cereus is typically grown as an ornamental plant for its bright blue epidermis and yellow spines. This species prefers full sun sitting in well draining soil and low humidity with high air flow. Water adequately in hot months of the year and keep dry during cooler months as this species is prone to rot. USDA hardiness zone 9 through 11. 

Browningia hertlingianus seeds require consistent moisture and humidity to germinate, but the soil should not be soaking wet. Cloning boxes, ziplock bags, and other containers that retain humidity are ideal to store sown pots. Use a well-draining sterilized soil mix. Seeds should be sown directly on top of the potting mixture and lightly covered with sand or potting mix, just enough to cover the seeds. Germinating pots should be kept indoors, out of extreme light and heat. Ideal germination temperatures range from 75°F to 85°F. Germination typically takes 3 to 6 weeks to occur. Even with optimal conditions, germination may be slow and sporadic.
