Dragon Fruit (Pitaya)
Selenicereus undatus
Family Cactaceae
Dragon Fruit saves its show for after dark: dinner-plate white flowers that open for one perfumed night per bloom, followed a month or so later by those magenta, green-scaled fruits that look invented for photographs. It is a cactus that behaves like an event calendar.
On a stout trellis in a big pot it climbs happily, sails through drought, and rolls indoors ahead of frost. For fruit, choose a self-fertile clone or grow two different ones, and keep a soft brush handy for midnight pollinating duty. Few plants earn their spot with better stories — give it the sunniest corner you have.

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.
