About

Selenicereus, from Ancient Greek σελήνη (selḗnē), meaning "moon", and Latin cēreus, meaning "candle", sometimes known as moonlight cactus, is a genus of epiphytic, lithophytic, and terrestrial cacti, found in Mexico, Central America, the Caribbean and northern South America. The term night-blooming cereus is also sometimes used, but this is also used for many night-blooming cacti, including Epiphyllum and Peniocereus. In 2017, the genus Hylocereus was brought into synonymy with Selenicereus. A number of species of Selenicereus produce fruit that is eaten. The fruit, known as pitaya or pitahaya in Spanish or as dragon fruit, may be collected from the wild or the plants may be cultivated.

Uses

The fruits of a number of species of Selenicereus (particularly those formerly placed in Hylocereus) are eaten. Selenicereus undatus and Selenicereus triangularis are widely cultivated in the Americas, Europe and Asia for their fruits, known as pitayas or pitahayas in Spanish, and as dragon fruits in Asia. The fruit of Selenicereus setaceus is eaten in South America.
