Yellow waterlily (Nymphaea mexicana)

With large floating leaves and bright yellow flowers, yellow waterlily forms dense infestations on waterways that reduce water quality and outcompete native plants. Scattered populations have been recorded in the Sydney region and it may be present in Hornsby Shire 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 yellow waterlily 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.
