Description
It is a very delightful epiphytic perennial cactus, that forms clumps about 30 cm high with a 60-100 cm spread. It’s a heavy bloomer and easily flowered plant that has the very appropriate and descriptive popular name, the “Red Orchid Cactus” For many years this species has aroused much controversy among horticulturists and botanists alike and it was assigned to the genus Epiphyllum by Haworth in 1829 but later some botanists considered it to be a natural hybrid between DisoSN'>8517' alt='8518'>Cactus phyllanthoides#SN#8518'>Diso[[Cactus phyllanthoidesSN' style='border
