Phalaris is a tufted, robust, deep-rooted temperate perennial grass, growing 1 to 2 m tall at maturity, and spreading by short underground stems (rhizomes). Main growth period autumn-winter-spring. Usually dormant in summer but can respond to summer rainfall particularly in cooler districts. Semi-winter dormant cultivars are slower growing in winter and less erect than winter-active cultivars.

Used widely in the inland high rainfall zone and adjacent higher-rainfall cropping areas of southern Australia for all types of grazing stock, but mainly sheep and beef cattle. Suitable also for hay and silage.
