Night-blooming cereus is the common name referring to a large number of 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. 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).
