Description: Serrated tussock is a perennial, drought resistant, tussock forming grass with a deep root system. Leaves are tightly rolled and rough to touch. Flower stalks usually appear in spring and are carried on slender,branched stalks slightly longer than the leaves. The flower head is slender and drooping, purple in colour, and produces one seed, about 2 mm long, pale straw coloured. A tussock in full flower presents a distinctly purple appearance due to the large number of purple florets. In winter, tussocks have a typical bleached golden colour.  A native of South America.

Problem: Serrated Tussock is a serious weed in New South Wales because it has low feed value and is unpalatable to sheep and cattle, it is hard to identify, tends to infest high-producing country, seeds prolifically and is readily dispersed by wind, water, animals and man and is particularly difficult and costly to control on non-arable land.
