I know this may be impossible, given the number of cultivars, but can you point me at some possibilities? My neighbor has this and does not know the name. It really is bright and catches the eye from a block away. He's sharing it with me. Yay!
Mid blooming, blooms are 5"-6", dormant and about 24" tall. It increases slowly but that might be his haphazard approach to weeding and such. The color is mind-blowing orange with a tiny hint of pink along the midrib and edges. Slightly ruffled. No rebloom that I've seen but he's only had it 3 years.
I looked at 'Mauna Loa' it was the only one in the data base with a picture that looked close and fit the other parts of the description and had a picture when I searched for orange daylilies with the other specs thrown in .
