A low evergreen shrub, whose stem, like that of Y. filamentosa, does not arise above ground-level, spreading by sucker growths. Leaves 1 to 13⁄4 ft long, 1 to 11⁄2 in. wide, green or glaucous, and bent downwards above the middle, long-pointed with straightish, thread-like fibres separating from the margin, and 2 in. or more long. Flowers as in Y. filamentosa, but borne on a downy, shorter panicle. Seeds dull, 1⁄3 in. long, produced in a capsule 2 to 3 in. long.
Native of the southeastern USA from N. Carolina to Alabama, with a more inland distribution than Y. filamentosa and Y. smalliana; introduced from Georgia and described by Haworth in 1819 from plants cultivated in his garden at Chelsea. The bent back apices of the leaves and the straighter marginal threads distinguish it from the two species mentioned, but its affinity is with Y. smalliana rather than with Y. filamentosa, having the leaves gradually tapered to the apex as in that species, and a usually downy panicle. It is rather more vigorous than either of its allies, and perhaps freer flowering, but its lax leaves can be damaged by wind.
