Spanish moss (Tillandsia usneoides) is an epiphytic flowering plant that often grows upon large trees in tropical and subtropical climates.

Most known in the United States, it commonly is found on the southern live oak (Quercus virginiana) and bald cypress (Taxodium distichum) in the lowlands, swamps, and marshes of the mid-Atlantic and Southeastern states, from the coast of southeastern Virginia to Florida and west to southern Arkansas and Texas.

Spanish moss consists of one or more slender stems, bearing alternate thin, curved or curly, and heavily scaled leaves 2–6 cm (0.8–2.4 inches) long and 1 mm (0.04 inches) broad.

The plant has no roots. Its flowers are yellow-green and small, with spreading petals. The scape is partly hidden within the leaf sheath.^[4] Spanish moss propagates both by seed and vegetatively by fragments that are carried on the wind and stick to tree limbs or that are carried to other locations by birds as nesting material.
