I just discovered i DO have a sort of purple daylily! About 3 years ago, a friend bought a big box of daylilies from Sam's Club...what a disappointment. We shared them out and there were supposed to be 3 different varieties (don't remember what they were now); almost none of the bloomed until last year and they were nowhere near the colors they were supposed to be: I know one was supposed to be this striking pale pink with red edges....it bloomed plain old yellow. Anyhows....looks like another clump finally bloomed this year and it's a sort of odd reddish purple. Just saw it this morning.
Yep I'm definitely going to be adding some daylilies. I just did a survey of the garden this morning and it's in that "July slump" where everything is green....very little in the way of color, especially in a few areas... Daylilies would be perfect this time of year.
