Yellow Water Lily

Yellow Water Lily
Invasive Plant
Yellow Water Lily
Nymphaea mexicana

Underwater tuber-like rhizomes send out rounded leaves that float on the surface. This exotic and invasive Water Lily produces bright yellow flowers. The plant needs a constant supply of water and quickly chokes dams, ponds or other still or slow moving bodies of water.



  • New plants are produced at the end of stolons and can become detached and float away to establish elsewhere.
  • Plants are exchanged amongst friends and people who do not recognise the invasiveness of this species.
