Cyperus brevifolius

Mullumbimby couch

Other common names:

Perennial greenhead sedge, short-leaf flatsedge.



Mullumbimby couch is a grass-like weed that grows year round and can be misidentified as nutgrass because of their shiny (light or bright) green leaves which are hairless and 1 to 3 mm wide. Mullumbimby couch spreads by above ground stolons and extensive underground shallow rhizomes. Roots are below every stem, which are triangle shaped in cross section, and can grow to 40 cm tall. The persistent perennial produces seedheads 6 to 7 mm long which have 3 or 4 green leafy bracts at the base and contain numerous small flower spikelets. Its 'seeds' are yellow to reddish-brown in colour. 


Mullumbimby couch thrives in wet conditions e.g. during the rain season.
