About: Epiphyllum hybrid

Epiphyllum hybrids, epiphyllums, epicacti, or just epis, also known as orchid cacti, which are widely grown for their flowers, are artificial hybrids of species within the group of cacti placed in the tribe Hylocereeae. In spite of the common name, epiphyllum hybrids mainly involve Disocactus species instead of Epiphyllum species, though Selenicereus grandiflorus and some unconfirmed Epiphyllum species were reportedly used for hybridization. Other sources include Pseudorhipsalis in the parentage of the group.
