Hylocereus undatus [Cactaceae]
Origin: Central America

Night-blooming cereus is a sprawling cactus that grows as vines which can spread across the ground or climb into trees. In other parts of the world it's cultivated for flowers and fruit, but in Hawaii fruits rarely form. The large white flowers, which open only at night, are prized in many gardens.

Brought to the islands in 1830, night-blooming cereus can now be found growing wild, especially near old house sites, military installations, and other former settlements. If left uncontrolled, it can form very large stands.

Flowering season in Hawaii occurs in the summer, from June to October.
