Red ludwigia (Ludwigia repens)

Red ludwigia is a creeping aquatic plant with red stems that can dominate waterways and outcompete native plants. It has been recorded 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 red ludwigia 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 seeds or plant fragments down stormwater drains.
