Waterlily, Lotus and aquatic plants

Welcome to the IWGS Aquatic Plant Database

The IWGS plant database is your number one up-to-date source for details on all aquatic plants.

In addition to discovering the latest waterlily (Nymphaea) and lotus (Nelumbo) varieties, you can use this database to:

  • determine the identity of your waterlily or lotus
  • find inspiration for what to grow this season
  • find award winning plants
  • see notes and photos posted by hybridizers and hobbyists
  • see if the plant you are looking for is sold by a nearby nursery or garden center using the Plant Finder tool.

Our database, which currently comprises over 3,000 plant names, and more than 1,000 photographs, continues to grow, with new varieties being added constantly. Register today and help the IWGS document and spread knowledge of waterlilies, lotuses and other aquatic plants!

As the official ICRA Registrars for Nymphaeaceae and Nelumbonaceae, the IWGS encourages hybridizers to register their creations. Registered plants will appear in the plant database after acceptance.
