Switchgrass is a warm-season native bunchgrass with a vertical, upright habit. Its attractive, fine-textured seedheads add a light and airy feel later in the season. It supports larval forms of several pollinator species, rather than serving as a direct source of nectar or pollen for adults.
5 to 9
3 to 6 ft.
2 to 3 ft.
Partial Shade, Full Sun
Does well in a wide varity of soil conditions in full sun but too much shade may cause this plant to loose its upright habit. Tolerates occasional flooding and drought.
Care and Maintenance
Mostly clump-forming but may spread slowly by rhizomes. Can be an aggressive self-seeder, clipping seedheads can help limit spread. Excellent winter interest from upright stems, delay cutting back until late spring when all stems may be cut to ground level or left between 8 to 24 inches to serve as an insect nesting site.
Pest and Diseases
No major issues.
Establishment and Propagation
Plant as a plug or start from seed, no pretreatment needed.
