Epiphyllum ({{IPAc-en|ˌ|ɛ|p|ᵻ|ˈ|f|ɪ|l|əm}};Sunset Western Garden Book, 1995:606–607 "upon the leaf" in Greek) is a genus of epiphytic plants in the cactus family (Cactaceae), native to Central America and South America. Common names for these species include climbing cacti, orchid cacti and leaf cacti, though the latter also refers to the genus Pereskia.

Description

The stems are broad and flat, 1–5 cm broad, 3–5 mm thick, usually with lobed edges. The flowers themselves are large, with diameters ranging from 8 to 16 cm,{{Citation needed|date=March 2025}} white through red,{{Cite web |title=Leaf cactus {{!}} Description & Facts {{!}} Britannica |url=https://www.britannica.com/plant/leaf-cactus |access-date=2025-03-12 |website=www.britannica.com |language=en}} with numerous petals. These flowers have notably short, nocturnal antheses, blooming only at night, and wilting at dawn.{{Cite journal |last=Smith |first=Leland |date=2024-03-11 |title=Epiphyllum phyllanthus subsp. rubrocoronatum in Nicaragua |url=https://bioone.org/journals/cactus-and-succulent-journal/volume-96/issue-1/015.096.0111/Epiphyllum-phyllanthus-subsp-rubrocoronatum-in-Nicaragua/10.2985/015.096.0111.full |journal=Cactus and Succulent Journal |volume=96 |issue=1 |doi=10.2985/015.096.0111 |issn=0007-9367}} The fruit is edible, very similar to the pitaya fruit from the closely related genus Hylocereus, though not so large, being only 3–4 cm long.{{Citation needed|date=March 2025}}

The broad-leaved epiphyllum (Epiphyllum oxypetalum) is particularly well known species that bears large, strongly fragrant flowers.{{Cite book |last=Lim |first=T.

Cultivation

The plants known as epiphyllum hybrids, epiphyllums or just epis, which are widely grown for their flowers, are artificial hybrids of species within the tribe Hylocereeae, particularly species of Disocactus. In spite of the common name, the involvement of Epiphyllum species as parents of Epiphyllum hybrids is unconfirmed.{{Cite journal|last=Van der Meer|first=M. H.
