Night-blooming cereus is the common name referring to many flowering ceroid cacti that bloom at night. The flowers are short lived, and some of these species, such as Selenicereus grandiflorus, bloom only once a year, for a single night,^[1] though most put out multiple flowers over several weeks, each of which opens for only a single night. Other names for one or more cacti with this habit are princess of the night, Honolulu queen (for Hylocereus undatus), Christ in the manger, dama de noche, and queen of the night (which is also used for an unrelated plant species).
