I tried to find Ono in the Database, but there were 6 pages of names with 'ono' in them, and I couldn't find the entry for "Ono".
I finally went to Google for a Daylily image, and found a page in Dave's Garden, and then eventually found this page, for which vic and joy had entered photos! Hooray! A little bit of detective work gets results.
Could there be an easier way of finding it?

Nora, so glad you found it. I don't have your answer but I bet @Calif_Sue does

The search has trouble with 3 letter and less words, just too many possibilities!
The best way, go the the Plant Database page and then on the right side is the box 'Visit our custom databases'. Click on Daylilies. Once you are on that page, then type in your cultivar name right under the Search and Browse box and the first one that pops up is 'Ono'!

Thank you Sue
