Nutgrass

Botanical name: Cyperus esculentus

Description

A perennial rapidly spreading grass-like sedge with flat tapered, slightly corrugated leaves. 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 tubers serve as energy storage for the weed which can make it difficult to control. Seeds from summer through autumn, with yellowish brown seeds arranged in narrow spikelets on an umbel like inflorescence. Propagated from both seed and tubers.
