Nymphaea and Nelumbo Plant Registrations
The International Waterlily and Water Gardening Society (IWGS) is recognized by the International Society for Horticultural Science as the official registrar for waterlilies (Nymphaeaceae) and lotus (Nelumbonaceae). The registrars’ purpose is to serve local, national and international horticulture through recording and clarifying areas of confusion in the naming and identification of cultivated plants in these families.
Cultivars of waterlilies and lotus are registered for two reasons: first to prevent, as much as possible, names that are already appropriated from being given to new hybrids, and second, to prevent the use of names which so closely resemble existing names that they would cause confusion. Names must also conform to the International Code of Nomenclature for Cultivated Plants.
Below you will find links to registration forms for both Nymphaea and Nelumbo cultivars. If you have any questions regarding the registration process, you may contact the appropriate registrar listed below.
