Parrot's feather (Myriophyllum aquaticum)

Parrot's feather is a common weed in coastal waterways of eastern Australia. It has been recorded at several locations in Hornsby Shire, and could be found in ponds, aquariums, fish tanks, water features, dams, and waterways, dumped in bushland or roadsides, or being sold online. Notify Council if you see this plant in Hornsby Shire or see evidence of it being traded (including online), carried, grown, or released into the environment. Try to avoid parrot’s feather from being introduced onto to your land. If you find it on your property, prevent it from spreading from your land where possible, especially into bushland areas, watercourses, and dams, or spreading plant fragments down stormwater drains.
