# Queen of the Night (Selenicereus grandiflorus)

> A legendary climbing, semi-epiphytic cactus native to Central America and the Caribbean, famed for producing nocturnal flowers spanning up to 30 cm in diameter. The dramatic blossoms unfurl for only a single night, releasing an intoxicating vanilla-orange blossom fragrance before withering at dawn. Its slender, multi-ribbed green stems produce abundant aerial roots that cling tenaciously to supports.
