Dragon Fruit Cactus

Hylocereus undatus, also treated as Selenicereus undatus, is a climbing cactus grown for dragon fruit; North Carolina Extension lists the former name as a synonym. Its long, three-winged green stems climb by aerial roots, and large fragrant white flowers open at night before edible red-skinned, white-fleshed berries form.

Full sun supports growth and fruiting, although newly planted vines can be injured by intense sunlight. Use well-drained soil or a well-drained cactus mix.

In Florida, harvest for H. undatus generally runs from June through November. Fruit set can vary among cultivars; some require pollen from a distinct genetic type.

Tie stems to the trellis and prune crowded or damaged growth so the plant stays supported and accessible for harvest. [UF/IFAS](https://ask.ifas.ufl.edu/publication/HS303)
