I've had 'Siloam Double Classic' here for many years and it's certainly hardy but currently it is in the shade of a tree and doesn't like it very much. It did flower this year but not much and I didn't get a good picture. If I recall correctly the earlier flowers this year were single also, which confused me initially since I'm trying to reconcile my faded label daylilies with my map! This is an older picture from years ago.
