I am quite certain others have commented on AHS daylily registration, but I want to add my two cents worth anyway.

The main problem with the process over all is the total lack of standards.

My beef today, though, is about blooming season. People who register daylilies seem to describe the plant as it appears to them, without regard to the conditions under which it has grown, in particular hardiness zone. Mid-season for me (zone 7a in northern Virginia) runs from early June to maybe mid-July. Most of my collection is done, or nearly done, for this year. A recent post, from a poster in New England, said their season has just started. Obviously, then simply saying that a hybrid blooms in mid-season doesn't mean squat. I have learned a lot more about blooming season from growers descriptions of their offerings (and personal experience) than I will ever learn from the AHS database.

I was just on the Tranquil Lake Web site checking out late season bloomers (I am always on the hunt for late season bloomers!) and they, like Bloomingfields, specify what their plants do FOR THEM. So if a plant blooms at Tranquil Lake in September it will probably bloom for me in August. That's the kind of information I need to make wise choices.

As an aside, you also can't trust what you find in local garden centers. I bought two cultivars that I found blooming in late July, assuming they would bloom into August. Surprise! Once established, they turned out to be mid-season bloomers.
