Cardinal wild pine (Tillandsia fasciculata) bromeliad, a species of epiphyte.
An epiphyte, also known as an airplant, is a plant that grows on another plant but which obtains no nourishment from it. Various lichens, mosses, ferns, and orchids are epiphytes, particularly on trees. Epiphytes thrive in warm, wet climates. Many solve the problem of obtaining water by developing aerial roots.
