Spanish Moss (Tillandsia usneoides) is a flowering plant that grows upon larger trees, commonly the Southern Live Oak (Quercus virginiana) or Bald Cypress (Taxodium distichum) in the southeastern United States. It closely resembles its namesake (Usnea, or beard lichen), but in fact it is not biologically related to either mosses or lichens. Instead, it is an angiosperm in the family Bromeliaceae (the bromeliads) that grows hanging from tree branches in full sun or partial shade. Spanish Moss grows from the southeastern United States (southern Virginia and eastern Maryland) to Argentina, growing wherever the climate is warm enough and has a relatively high average humidity. The plant has no aerial roots and its flowers are tiny and inconspicuous. It propagates both by seed and vegetatively by fragments that blow on the wind and stick to tree limbs, or are carried by birds as nesting material.
Spanish Moss has been used for various purposes, including building insulation, mulch, packing material, mattress stuffing, and fiber. In 1939 over 10,000 tons of processed Spanish Moss was produced. It is still collected today in smaller quantities for use in arts and crafts, or for beddings for flower gardens. It is also known to have been worn by the women of the Timucua Indian tribe.
