An epiphyte (air plant), Spanish moss does not root in soil, but attaches itself to a tree or other tall object where it can secure light and moisture. Epiphytes are not parasitic; they live on airborne moisture and dust particles, which they absorb mainly through specialized leaves and, in many species, also through aerial roots that anchor the plants, as well. The fleshy leaves of epiphytic orchids serve as food and water reservoirs. The leaves of some bromeliads are arranged to trap rainwater, or contain scales that open and close during moist or dry periods. In temperate regions many mosses, lichens, algae, and liverworts are epiphytes, as are many ferns and cacti in tropical and subtropical areas. Spanish moss and the popular houseplant staghorn fern are familiar air plants.see also moss
