Perennial, clumping herb < 1 m tall. Leaves are pinnate and < 22 cm long. Flowers are pea-like, purple/white and borne in spikes. Seed pods are < 4 cm long.
To help protect our environment:
Riverbeds, riparian margins, pasture, roadsides, wasteland.
Seeds dispersed by explosive dehiscence, gravity and water. Human-mediated dispersal through movement of contaminated soil and gravel.
Toxic to livestock. Potential to act as nitrogen fixer and compete with native plant species.
Follow up treated areas 3 times per year. Encourage natural regeneration of native plants or replant treated areas where possible after 2-3 treatments to establish dense ground cover and minimise reinvasion.
CAUTION: When using any herbicide or pesticide please read the label thoroughly to ensure that all instructions and safety requirements are followed.
