- Flora of Virginia Name/Status
- Agrostis perennans (Walt.) Tuckerman
- Although most grass taxonomists don't recognize infraspecific taxa in Agrostis perennans, this species exhibits considerable morphological and ecological variation that seems worthy of additional study. A delicate, lax, divergently branched, early-flowering form with long-pedicellate spikelets has been called var. aestivalis Vasey and is frequent in shaded seeps, seepage swamps, and other saturated wetlands in Virginia. It produces panicles in June, one to two months before the more robust forms of upland forests and weedy habitats begin to flower. See also map and comments for var. elata.
- Ubiquitous in mesic to dry upland forests, woodlands, barrens, clearings, meadows, and other open habitats; also in varied wetlands, especially
depression swamps and ponds, bogs, fens, and seepage swamps. Common throughout.
