Though it is sometimes referred to as a night-blooming cereus, it is not closely related to any of the species in the tribe Cereeae, such as Selenicereus, that are more commonly known as night-blooming cereus. All Cereus species bloom at night and are terrestrial plants; Epiphyllum species are usually epiphytic.
The species is widely cultivated as an ornamental plant for its flowers. In areas too cold for winter survival, it can be grown as an annual plant. Since it is of tropical origin, it flowers best under a summer short-day photoperiod. Though it can be successfully flowered in the north, its flowering is impaired by excessively long summer days.

Fertile plants have a single stem with two palmately lobed leaves. [6] Flowering plants produce a single terminal flower with no petals and three sepals and 12 or more conspicuous white pistils; flowering occurs for a short time in spring. [6] Fertilized flowers grow into red, raspberry-like fruits with one or two seeds. [6]
