It's been a bit of a problem as often hybridizers use different terms or words to try to describe their intro and as sooby and Char pointed out, sometimes their descriptions has no actual connection to an actual registered patterned daylily.
Dave has added several descriptive words that get picked up in the descriptions of the registrations and because of the way a hybridizer may write it, it lands in an incorrect bloom trait. For instance, some mention a small ruffled edge and now that word 'edge' lands it as an official Edged daylily. We have had trouble with the tooth/fringe category because different words get used by the hybridizer.
Char has done a tremendous amount of work editing new intros to properly reflect the correct search aspects.
If any of you have any suggestions of terms that may be needed to increase the accuracy for any search, please let us know and we'll see if we can all come to a consensus for making any needed features that we can request Dave to add.
The AHS hybridizers are a prolific group of happy daylily growers, they just hit the 100,000 mark of registered daylilies (and it was one of Char's intros that officially hit that number
) and so strides in hybridizing brings changes and we will try to keep up in our database!
