Mullumbimby couch is a perennial grass-like sedge up to 15 cm high with dark green, glossy, strap-like leaves. It has tough, long rhizomes that are red to purple in colour and triangular stems in cross-section which is characteristic of sedges.
This sedge is in mostly observed in flower through spring and summer and presents as a single round, compact spike with three short, curved leaves protruding from the base of the seed head.
Mullumbimby couch grows best in areas of wet soils (like all sedges) and can be difficult to control due to its tough rhizomes from which individual plants regenerate. It is propagated through both seed and rhizomes.
