|A Pitaya or Pitahaya is
the fruit of several cactus species, most importantly of the genus Hylocereus
(sweet pitayas). These fruit are commonly known as Dragon fruit. Native
to Mexico and Central and South America, the vine-like epiphytic Hylocereus
cacti are also cultivated in Asian countries. Hylocereus blooms only at
night; the large white fragrant flowers of the typical cactusflower shape
are among those called "moonflower" or "Queen of the Night". Sweet Pitayas
have a creamy pulp and a delicate aroma.
