General Biology. Growth form. Herb. Life form. Annual. Reproduction. Seed. Dispersal. Wind, adhesion, soil movement.
Notes. Pollinated by bees, wasps, butterflies and spiders. Fruits have both pappus and hairs, so are easily dispersed by wind. Has generally faster, less variable and higher germination rates compared with native annual species, giving it a competitive advantage. Can be abundant immmediately post-fire in banksia woodland, particularly after autumn rather than spring burning, and then declines over time. Responds more positively to higher nutrient additions than native annual Asteraceae species, thus may have a competitive advantage in nutrient enhanced situations, particularly following fire.
