Flowers are a terminal radiating cluster of spikes from a whorl of leaf like bracts. Seedhead are purple to reddish brown, formed at the end of triangular stem (McCarty et al., 2008). Nutgrass spreads via rhizomes, roots, tubers, basal bulbs and occasionally seed. Tubers are oblong, covered with hairs and found in chains connected by brown and/or white wiry rhizomes (McCarty et al., 2008).
