I can't find it
Where on the search form is it?
I see Bloom size / class, Flower form and Bloom season, but nothing that says nocturnal??
I think Sabrina means the ATP database rather than the AHS one. The ATP search for daylilies is here and there's a check box for nocturnal:
To search for nocturnal in the AHS database you have to use the search box on the home page rather than the database search:
You have to sift through the AHS results, the database entries will say AHS Daylily Cultivar and then the nocturnal cultivar's name. There is an easier way of searching the AHS Database using Google and only getting database results but it's a bit more complicated. Go to Google Advanced Search:
and enter nocturnal, then under site or domain enter: http://www.daylilies.org/Dayli...
and that should search only the AHS database for characteristics that are entered but not in their own advanced search capability. Sounds more complicated than it is
