· 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
