I am continuously updating this new feature as new daylilies are purchased for my zone 5A "ish" garden. It may be a useful tool in choosing the right plants for your garden. This database reflectsmany of the cultivars. Most hybridizer pages are up-to-date. Some of the hybridizers are no longer available for various reasons. Just click on the name link. You can also click on the name on each page to go to that particular hybridizer's website.
