Dragon fruit

A pitaya /pᵻˈtaɪ.ə/ or pitahaya /ˌpɪtəˈhaɪ.ə/ is the fruit of several cactus species indigenous to the Americas.Pitaya usually refers to fruit of the genus Stenocereus, while pitahaya or dragon fruit refers to fruit of the genus Hylocereus.

These fruits are commonly known in English as "dragon fruit", reflecting its vernacular Asian names. The names pitahaya and pitaya derives from Mexico, and pitaya roja in Central America and northern South America, possibly relating to pitahaya for names of tall cacti species with flowering fruit.

Pitahaya-producing cacti of the genus Hylocereus are originally native to Mexico. They were transplanted to Central America, probably by Europeans. They are cultivated in Southeast Asia, the United States, Israel, Australia, Cyprus, and the Canary Islands.
