]. It spreads by means of by seed and broken stem fragments. Each flower head can produce over 4000 viable seeds - these can survive in water and are spread during annual flooding events and in mud attached to the fur or hooves of animals. Waterbirds may also be responsible for spreading seed. Broken stem fragments can be carried to new locations by floodwaters, and then take root in moist soil.
