Queen of the Night Cactus Trivia Questions

It belongs to the cactus family (Cactaceae), genus Epiphyllum, and is unrelated to orchids.

The blooms of Epiphyllum oxypetalum can reach 30 cm (12 inches) across and emit a sweet, vanilla-like fragrance to attract night pollinators.

It’s actually a tropical epiphyte from Central and South American rainforests, not a desert species.

Its common name 'orchid cactus' comes from the flower’s resemblance to orchids, though it is indeed a cactus.

The spectacular flowers open after dusk and wilt before dawn, making each individual bloom a fleeting, single-night event.

The fruit of Epiphyllum oxypetalum, commonly called Queen of the Night Cactus, is edible and safe to consume, with a mildly sweet taste.

In the wild, nectar-feeding bats and hawk moths are its primary pollinators, lured by its white color and strong scent.

Blooming is triggered by day length and temperature, not sudden darkness; this myth likely confuses it with poinsettias.
