Provenance provides the history of and chain of ownership of plants pictured on this web site. Each image in the cultivar and species galleries has been researched to the best of our ability for accuracy. We have asked contributors of images to provide information about where they obtained or photographed plants pictured to further insure accuracy. Print references for waterlilies can be found in the Bibliography of Names. Images have also been reviewed by acknowledged experts. When possible we provide this provenance from the hybridizer, back to the hybridizer or, for older cultivars, back to an expert source.

Why is providing this information important? There are a huge number of inaccurate images on the Internet and, unfortunately, a huge number of misnamed waterlilies and other aquatic plants being sold, traded and grown. If you are interested in knowing that the plant you are growing (and possibly passing on) is true to its name, you need a reference you can trust. In our galleries, we have compiled thousands of images from many of the world's leading authorities and best photographers; Provenance pages provide the credentials of the people and the plants.

For convenience of the reader, Provenance pages open in a new window when clicked from the Species and Cultivar Galleries. They are not linked back to the galleries. As a result, the pages in this Index are not linked to their respective galleries but are provided here as a matter of interest. At this time, Provenance pages are not provided for species and cultivars with only one image available though each has provenance in our files. In the case of several hybridizers who have provided all the images of their cultivars, provenance appears on the Gallery page.
