The purpose of the International Waterlily and Water Gardening Society (IWGS) Certified Collections is to provide international recognition to collections of Nymphaea and Nelumbo around the world. In return the collections offer an opportunity to IWGS members and the general public to experience and reference the diversity of the genera of Nymphaea and Nelumbo.

The collections are critical to the conservation of these genera as they help promote interest within the gardening audience. Some of the Certified Collection sites may work with the IWGS to conduct plant trials and grow out the New Waterlily Competition plants for judging. The IWGS Certified Collection sites will have the full endorsement of the IWGS in projects that are related to its mission, as interpreted by the IWGS board of directors, e.g. letter of recommendation for grants/ funding; networking with hybridizers and growers; help in sourcing plants; displaying New Waterlily Competition Lilies at certified sites etc. The IWGS Certified Collections will be advertised on the IWGS website and in other appropriate publications as one of the IWGS Certified Collections of Nymphaea and/or Nelumbo.
