About this weed

Originally from north Africa, temperate western Asia, southeastern and southwestern Europe, Shivery Grass was probably introduced as a seed contaminant in crops and as ornamental plants.

Description

Shivery Grass is a slender, annual, tufted grass growing to 0.5m high with a loose cluster of small shivering, nodding green spikelets that are small and more numerous than B. maxima. The spikelets are produced in spring and the seedbank persists for up to 3 years. Fire promotes germination of soil-stored seed.

Impact on Bushland

Not available.

Location

Widely distributed in the South-West Province in gardens, wastelands, wetlands and granite rocks. Shivery Grass prefers loam, sand, clay and laterite soils. In southern Western Australia it is a problem in cereal crops.

Priority for removal

Unknown: if established may impact native plant communities.
