Redhead grass is a bay grass with flat, oval leaves that wrap around the base of straight, slender stems. It grows in fresh to moderately brackish tidal waters in the Maryland portion of the Chesapeake Bay watershed.
Redhead grass is made up of straight, slender stems that are reddish or whitish and flat, oval leaves with curled edges and visible veins. Leaves grow in an alternate or slightly opposite pattern. The base of the leaves wrap around the stem. Spikes of tiny flowers that poke above the water’s surface in early-mid summer. Redhead grass has an extensive root and rhizome system.
Grows in fresh to moderately brackish tidal waters that have a slow current and a firm, muddy bottom.
Found in the upper to middle Chesapeake Bay and in many Maryland rivers; not recently documented in Virginia.
Migratory waterfowl feed on redhead grass.
Reproduces sexually in early-mid summer when flowers are pollinated and the plants produce dark-colored fruits that contain seeds. The fruits eventually mature and sink to the bottom, releasing the seeds. Reproduces asexually when buds that develop over the summer produce shoots the following spring.
