Yellow Nutsedge (Cyperus esculentus )

Perennial, grassy

RANGE: Throughout the United States. A related species, purple nutsedge, is especially prevalent in the Southeast.

APPEARANCE: Though it resembles a grass, yellow nutsedge is actually a sedge. Its coarse, light green leaves grow upright from triangular stems. Seed heads appear from July to October.

 

GROWTH: Reproduces mainly from underground tubers; however, they can reproduce by seeds and underground stems. Tubers store food and are drought tolerant. Yellow nutsedge grows vigorously in summer, especially under moist conditions; primarily troublesome in closely mowed lawns.
