- cool-season creeping perennial grass with slender, upright leaf blades with red tips
- forms dense colonies that spread slowly to quickly
- remove any all-green-leaved sprouts in colonies as they are quite invasive
- green-leaved form is called cogongrass, a very serious noxious weed in southeastern U.S.
- flowers are not too showy--small panicles within the 1-2 foot tall foliage
- prefers moist, fertile soils; full-sun to part shade
- does not do well in dry soils, particularly in full sun
