The illustrated growing guide
Dragon Fruit (Pitaya)
Selenicereus undatus
Family Cactaceae
Est. zones 10-11

A climbing cactus that throws dinner-plate flowers open for a single perfumed night — set your alarm and hand-pollinate with a brush for magenta fruit. Grows huge in a pot on a trellis; drag it in before frost. Buy a SELF-FERTILE clone or two different ones.

VIII
Questions
Dragon Fruit (Pitaya) questions, answered straight.
Why isn't my dragon fruit (pitaya) fruiting?
Most often: it has no genetically distinct partner nearby. Dragon Fruit (Pitaya) can't pollinate itself — many types need hand-pollination at night (flowers open once, after dark) or a second clone. Plant a second, unrelated one nearby; two different cultivars, or a cultivar plus a seedling, is the classic pairing.
Is dragon fruit (pitaya) safe for kids and pets?
Dragon Fruit (Pitaya) is commonly eaten and isn't considered toxic, but "commonly eaten" isn't a guarantee for any particular person or animal — allergies, quantity, and which part you eat all matter. Never eat a plant you haven't positively identified, and check with a vet before letting pets or livestock graze anything new.
When do you harvest dragon fruit (pitaya)?
Fruit 30-50 days after bloom, summer-fall.
