Old-witch grass
Panicum capillare
Old-witch grass is a native annual ornamental grass valued for its airy, cloud-like seed heads that add movement and texture to naturalistic gardens and prairie plantings. It grows best in full sun with minimal watering and thrives even in poor, sandy soils. It self-seeds freely, so deadhead if you want to limit its spread.
