Panicum amarum (Bitter Panic Grass) [30 Seeds]


Germination Information: There isn’t much information available on growing this species from seed. I do find self-sown seedlings in my garden, so one route that obviously could work is sowing in fall or winter and leaving the pot outdoors; then the seeds can sprout when conditions are right. Or, you could try sowing in warm, bright conditions; if no seedlings appear in about a month, then give the pot an artificial chilling period of about 2 months. Either way, I’d suggest surface-sowing (pressing the seeds into the surface of the growing medium).

Transplant the seedlings (in groups) to pots when they’re 1 to 2 inches tall. Use groups of 6 to 10 or so if you want bigger clumps faster, or 3 or 4 per pot if you want a larger number of starter plants.

Note that this information will not appear on the seed packet you receive.

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 late September 2022. At least 30 seeds. Unknown ecotype.
