Selenicereus undatus
Selenicereus undatus is a climbing, night-blooming cactus that grows as a vine on trees or rocks, and is also cultivated as the white-fleshed dragon fruit. The key to growing it is bright light, a well-drained mix, and a sturdy support to climb.
Selenicereus undatus, the white-fleshed pitahaya, is a species of the genus Selenicereus (formerly Hylocereus) in the family Cactaceae and is the most cultivated species in the genus. It is used both as an ornamental vine and as a fruit crop, the pitahaya or dragon fruit.
Like all true cacti, the genus originates in the Americas. S. undatus is native from Mexico to Honduras; it may be a hybrid.
Selenicereus undatus is lithophytic or hemiepiphytic. It is widely distributed through the tropics in cultivation. It is a sprawling or vining, terrestrial or epiphytic cactus. They climb by use of aerial roots and can reach a height of 10 meters (33 feet) or more growing on rocks and trees.
