Epiphyte ( Tillandsia usneoides ) in the pineapple family, found in southern North America, the West Indies, and Central and South America.
It often hangs in large, beardlike, silvery-gray masses from trees and other plants and even on telephone poles, but it is not parasitic or structurally intertwined with its host. It takes in carbon dioxide and rainwater or dew for photosynthesis through tiny, hairlike scales that cover its threadlike leaves and long, threadlike stems. It absorbs nutrients from dust and solvents in rainwater, or from decaying organic matter around its aerial roots. Stalkless yellow flowers appear rarely. Spanish moss is sometimes used as a filler in packing boxes and upholstery, and around potted plants or floral arrangements.
