Epiphyllum, Orchid Cactus, ‘Ric Rac’, Ephiphyllum hybrid, Cactaceae, 4in potted plant Name: Orchid Cactus ‘Ric Rac’ Scientific Name: Ephiphyllum hybrid Family: Cactaceae 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, Pseudorhipsalis and Selenicereus. In spite of the common name, Epiphyllum species are less often involved as parents of Epiphyllum hybrids. The parent species from which epiphyllum hybrids were bred are different in appearance and habit from most cacti. They are found in the tropical forests of Central America where they grow as climbers or on trees as epiphytes. They have leafless (or apparently leafless) flattened stems which act as the plant's photosynthetic organs. Relatively large flowers are borne on the sides of the stems; in many species they open at night They are fast growing plants and should flower within two years. Epiphyllum hybrids should be re-potted every 2 to 3 years as they tend to deplete the nutrients in their growing medium
