Water poppy (Hydrocleys nymphoides)

Water poppy is an aquatic plant that can form dense infestations that choke waterways. It has been recorded being sold in Hornsby Shire and could occur in aquariums, fish tanks, water features, and waterways, dumped in bushland or roadsides, or being sold online. Notify Council if you see water hyacinth in Hornsby Shire or see evidence of it being traded (including online), carried, grown, or released into the environment. Try to avoid this plant from being introduced onto to your land. If you find water poppy 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.
