The American Hemerocallis Society, Inc. (AHS)
I am a member of the society and their services are greatly appreciated!
All original registration information and photographs on this site are courtesy of the AHS website, daylilies.org. Their site provides helps on growing, frequently asked questions, and a daylily dictionary of terms.
The site also includes a searchable database of all officially registered daylilies (currently around 85,000 cultivars/varieties). Start your search here.
