Serrated tussock (Nassella trichotoma)
Description: Perennial tussock-forming bunchgrass that can live up to 20 years. Usually grows up to 2' in height with a deep fiberous root system.
Life Cycle: Herbaceous perennial.
Habitat: Pastures, roadsides, grassland, grassy woodland.
Leaves: Long, stiff, narrow leaves. Fine serrations on leaf blade. Small flap or ligule located at the junction of the leaf blade and the leaf sheath.
Flower: When flowering, the plant can appear purple, turning a golden brown colour as the seeds mature.
Fruit: Seeds enclosed in two reddish-brown or purple bracts.
Root: Diffuse, fibrous.
The problem is…serrated tussock is a prolific seeder with 90% of the plant being self-pollinated. Once established the weed will remain for many years.
