Eustachys glauca

Eustachys glauca, the saltmarsh fingergrass, is a species of grass native to the southeastern United States.

This perennial grass grows up to 4 feet tall. The dark green, folded leaf blades are 12 to 14 inches long and have rounded tips. The ligule is a tiny fringe of hairs. The seedhead is made up of 15 to 20 long spikes, each up to 5 centimeters long. The brown spikelets are arranged along one side of each spike. The grass grows for a long time during the year and may produce 2 or more crops of seed in a season.

This grass grows in coastal habitat, such as marsh land and sloughs. It prefers calcareous soils.

This grass provides a good graze for livestock, but overgrazing will kill it.
