Luzula luzuloides is a perennial woodrush that grows in tufts. Flowering culms can be 45-70 cm (18-28 in.) in height. The leaves of this plant are long, tapering to a point, and are hairy especially at the margins. The leaves measure around 30 cm (12 in.) long and 7 mm (0.25 in.) wide. This plant flowers and fruits in the late spring and summer. The flowers are in clusters of two to eight and are whitish to pinkish in color. These flowers are arranged in a loosely branched inflorescence. The petals measure 3-3.8 mm (0.15 in.) long. The bracts are brownish to clear and the tips look as if they are torn. The fruit are reddish capsules that are round to oval in shape, measuring 2 mm (0.08 in.) long. The ellipsoid-shaped seeds are dark brown and shiny and measure 1 mm (0.04 in.) in length.

Luzula luzuloides spreads vegetatively by means of stolons. Seeds are passively dispersed from the ripened capsules.
This plant is native to central Europe. In the United States it is distributed from Maine to Pennsylvania and west to Minnesota. In New England it has been reported from Maine, Vermont, Massachusetts and Connecticut.
HISTORY OF INTRODUCTION IN NEW ENGLAND
It is not known how Luzula luzuloides was introduced into New England. It is possible that it was introduced by accident, though there is some indication that it may have been planted intentionally (Howard 1978). The earliest records of this plant in New England are from 1910 from Norfolk Country, Massachusetts and 1912 from Maine.
HABITATS IN NEW ENGLANDAbandoned Field, Early Successional Forest, Edge, Floodplain Forest, Open Disturbed Area, Pasture, River or Stream, Vacant Lot, Yard or Garden
Luzula luzuloides is most often found in open woods, fields and lawns.
Luzula luzuloides has the potential to invade unmanaged habitats such as open woods. It spreads vegetatively and could displace native plant species.
