Bitter panic grass (Panicum amarum), also known as coastal switch grass, is a clump-forming, warm-season grass with grayish green foliage that turns yellowish in fall. Its flowering stems start out upright, reaching around 6 feet tall by late summer, then gradually lean outward as the arching, lacy sprays of seeds form in late summer into fall. This U.S. native can be a handsome substitute for miscanthus in a medium-sized to large garden or landscape. Full sun. Perennial; Zones 3 to 9.
Collected in October 2020. At least 30 seeds.
