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. Cloud Nine switch grass is an tall upright grass up to seven feet in height and about two to three feet in width. Spring foliage is a bluish-green which turns yellow-brown by fall and persists throughout the winter months if the plant is not cut back. Like most switch grasses, Cloud Nine 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 Cloud Nine is mostly grown for its ornamental value, it is generally retained for its autumn and winter interest while also providing shelter for wildlife. Cut back the foliage to near ground level in late winter.
