Native to Europe and Asia.
Tufted or shortly rhizomatous perennial grass with smells of coumarin when crushed. Leaves are hairless or sparsely hairy, flat and grow to 20 cm long and 2-8 mm wide. Flower-heads are dense, spike-like panicles, 2-10 cm long. Spikelets have 3 flowers but only one is fertile. The sterile spikelets are awned; one being straight to 2-4 mm long and the other sharply bent and 6-9 mm long.
Common weedy species of pastures and waste ground throughout the cooler parts of the State. Often found as part of fringing vegetation around lakes and swamps and along water courses but doesn’t appear to be particularly tolerant of waterlogging. Is tolerant of acid soils.
