Switch Grass Panicum virgatum

Other Name: Tall Panic Grass


Description: It is a native, warm-season, sod-forming perennial grass. It begins growth in late April or Mid-May. The height of Switch Grass is up to 2 meters, but usually somewhat less than that attained by Big Bluestem or Indian Grass. Switch Grass is a lighter shade of green than the other grasses and has a lacy, open look.

 

Leaf: The Leaves of Switch Grass are persistent on the plant into winter, and are closely grown to give the lower half of the plant a dense growth appearance.    

 

Flower: The tops of the stems have large clusters of many slender branches bearing the tiny, budlike flowers. These branches spread widely away from the main stem, with scattered individual flowers near the tips of the branches. Each flower appears to have 3 small, pointed, overlapping bracts. The tear-drop shaped seeds are small and get inside pant legs and into stockings.

 

Stem: The green to purplish stems are stout. 

 

Blooming months: Late July-September

Discussion: Switch Grass is palatable in its early growth and is readily eaten by all kinds of grazing animals. It is easily established. It also provides good nesting habitat for prairie birds.

 

Distribution: Switch Grass may be found over all the True Prairie and Mixed Prairie areas of central United States and the southern Prairies of Texas.
