Nutgrass (Cyperus Rotundus)

Nutgrass is a perennial rapidly spreading grass-like sedge with flat, tapered and corrugated foliage. The stem is triangular in cross-section, a feature which is unique to sedges. The name nutgrass comes from the nut-like tubers found on rhizomes under the surface. These “nuts” serve as energy storage for the weed which are the reason the weed is difficult to control.

The weed seeds from summer through to autumn, with yellow-brown seeds arranged in narrow spikes. Nutgrass propagates from both seed and tubers.
