Princess of the Night Dragonfruit is a night-blooming cactus native to Caribbean islands and Mexico that produces edible fruit on climbing, sprawling stems. This Selenicereus pteranthus variety earns its romantic name from its spectacular nocturnal flowers, which bloom at night and stay open into late morning, followed by the development of dragonfruit. The thick, green stems with purple-tinged edges can reach over 10 feet long with segments up to 2 inches in diameter, making this a dramatic vertical grower that thrives in full sun and handles drought with ease.

The Princess of the Night captivates gardeners with its dual purpose: stunning night-blooming flowers that eclipse nearly everything else in the cactus world, followed by the reward of homegrown dragonfruit. Its Caribbean and Mexican heritage gives it proven resilience in tropical and warm subtropical climates. Grown on a sturdy trellis or allowed to cascade, it becomes both ornamental showpiece and productive fruit plant, with strong fruit production and reliable growth rated at 4 out of 5.
Princess of the Night Dragonfruit is grown primarily for its edible fruit, which can be eaten fresh, scooped directly from the skin and enjoyed for its sweet flesh and tiny black seeds. The fruit also lends itself to smoothies, juices, and desserts. Beyond culinary use, the plant is treasured by cactus enthusiasts and night gardeners specifically for its nocturnal blooming spectacle, making it as much an ornamental specimen as a fruit producer.
No timeline data available yet for this variety.
Dragonfruit typically develops after flowers fade in late morning. Harvest fruit when the skin turns from green to deep pink or reddish, depending on maturity stage. The fruit should feel slightly soft when gently squeezed. Use a sharp knife or pruner to cut the fruit cleanly from the stem, leaving a short stub. Handle carefully as the segments have spines.
Prune to manage size and direct growth along your trellis or support structure. Remove damaged or dead segments regularly. Light pruning after flowering encourages branching and denser growth, which supports better fruit production. Avoid heavy pruning during the blooming season so you don't sacrifice flowers.

“This variety originates from the Caribbean islands including the Bahamas, Cuba, and Haiti, as well as Mexico, where it evolved as a climbing cactus in tropical forests. The Selenicereus genus has a long history of cultivation among indigenous peoples and later colonial gardeners who prized both the spectacular flowers and the edible fruit. The common name 'Princess of the Night' reflects the romantic European fascination with its nocturnal blooming habit, a trait that distinguished it from day-blooming ornamental cacti and made it a coveted specimen in 19th and 20th-century nursery collections.”
