HORTICULTURAL
Plant Sale Text: Indian Grass is a primary component of tall-grass prairies in the west, but is found mostly along roadsides and in old fields east of the Appalachians. It is often used in restorations of fields that have become dominated by fescue because of high-quality wildlife habitat. Ground-nesting birds such as quail depend on Indian Grass and other warm-season grasses for habitat and food. Besides its use for wildlife habitat restoration, Indian Grass is an attractive grass for landscape. As it begins to go dormant in late fall this entire grass takes on golden hues. Effective when used en masse, the golden tips sway gently in the breeze providing movement to the garden.
