Notes: Autumn and spring germinating perennial. Seedlings grass-like. Serious winter growing weed of cereals and pastures in temperate Australia. It may contaminate milk, meat and grain with an onion odour. Clusters of bulbils shatter readily into individual bulbils and cannot be separated from cereal grain because of their size and shape.
