- Description
-
Purple Small-Reed is a long-lived perennial grass that is native to Europe and Western Siberia. It is loosely clump forming and found in large swaths in salt marshes and wet habitats and can spread quickly by its shallow rhizomes. It is not commonly found in North or South America. Note that Calamagrostis brachytricha (Foxtail grass) is a good substitute for planting in the Southeastern United States.
A slender stem with no lateral branches holds a large, slightly nodding branched inflorescence, which has many tiny hairs that look like an eyelash. This inflorescence turns purple when in flower, giving the grass its common name. The inflorescence turns tan later in the season. The leaf blades are flat with entire margins and hold their shape well in winter.
