Switch grass was an important part of the tall grass prairie
providing an important food source and winter shelter for a range of
insects, small mammals and birds, even bison.

Heiliger Hain switch grass is an upright grass of about four feet in height and about three feet in width. Spring foliage is a bluish-green which turns dark maroon by summer and persists throughout the winter months if the plant is not cut back.

Like most switch grasses, Heiliger Hain is extremely versatile and can cope with a range of soil types from sandy to clay and shade conditions although it prefers full sun. Because of its versatility it can be used in a range of conditions such as rain gardens, stabilization of eroding banks, and black walnut. Since Heiliger Hain is mostly grown for its ornamental value, it is generally retained for its autumn and winter interest. Cut back the foliage to near ground level in late winter.
