Deertongue panicum (Dichanthelium (formerly Panicum) clandestinum) is a clump-forming, cool-season grass with broad, tapering, bright green foliage and sprays of tiny green blooms in early to midsummer, followed by airy clusters of small seeds in mid to late summer. Apparently the species produces flowers and seeds again later in the season too; I have to admit that I haven’t noticed that. Height is generally around 3 feet. You usually often see deertongue panicum in ornamental gardens, perhaps because it can get somewhat sprawly as the season progresses. But if you have a wildish meadow or woodland area, it’s worth having for its wildlife value: as a source of food for a variety of native insects (the foliage) and wild birds (the seeds). Native to much of eastern North America. Full sun to partial shade; average to moist soil. Perennial; Zones 3 to 8.
Collected in August 2020 from plants that grow wild in somewhat shady parts of my meadow in Milford Township, Bucks County, PA. At least 25 seeds.
