Dr. John Wiersema is an acknowledged expert on the identification of waterlilies.
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. 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.
