Serrated tussock (Nassella trichotoma)

Description: Perennial tussock-forming grass.

Life Cycle: Herbaceous perennial.

Habitat: Pastures, roadsides, grassland, grassy woodland.

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.

Leaves: Long, stiff, narrow leaves. Fine serrations on leaf blade.

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.
