Queen of the night (Epiphyllum oxypetalum)
Description
Epiphyllum oxypetalum (Dutchman's pipe cactus or queen of the night[citation needed]) is a species of cactus and one of the most cultivated species in the genus. E. oxypetalum blooms rarely and only at night, and its flowers wilt before dawn. Though it is sometimes referred to as a nightblooming cereus, it is not closely related to any of the species in the tribe Cereeae, such as Selenicereus, that are more commonly known as nightblooming cereus. All Cereus species bloom at night and are terrestrial plants; all Epiphyllum species are usually epiphytic.
