Panicum virgatum

Common Name: Switchgrass

Switchgrass is a warm-season perennial grass that grows 3 to 6 feet tall, forming dense clumps. It is found in prairies, savannas, and along roadsides, thriving in a variety of soils, including sandy and clay-rich ones. Its deep root system helps prevent erosion, making it valuable for restoration projects. Switchgrass is very versatile in native landscaping projects due to its adaptability to different soil types and conditions. It turns a striking golden hue in the fall and provides winter interest.

Sowing Information

For most homeowners, the recommended method is to hand-broadcast seed at a minimum rate of 16–64 PLS (Pure Live Seed) ounces per acre. To ensure even coverage, broadcast the seed in perpendicular passes across the site. Grass seed should be broadcast first and lightly raked into the soil. Afterward, apply a light mulch layer using clean, seed-free straw or, preferably, our native Little Bluestem straw, available at our retail garden centers. Once mulching is complete, broadcast native wildflower seed over the area without raking it in. A good rainfall or thorough watering will provide sufficient soil contact for successful germination.

Planting Information

Dig a hole in your planting site slightly larger than the plant’s root system. When placing the plant into the hole, ensure that the soil line remains consistent with its original level in the pot. Fill in around the roots with the excavated soil, gently firming it to eliminate air pockets. Water the plant thoroughly the same day to promote successful establishment.
