Panicum virgatum is an attractive, warm season grass with airy panicles. Primarily clump forming, this grass may naturalize by rhizomes and self-seeding to form colonies. Has a stiff, column-like form and reaches 3-6 feet tall.
This grass is outstanding for erosion control and wildlife cover. The deep, fibrous root system helps to hold soil in place, preventing erosion, while the height of the grass helps form a wind erosion barrier. The grass provides cover for many animals, including upland game birds and songbirds. Additionally, the seeds provide food for birds.
