I have my 1st daylily purchase made maybe sometime in early 90's and of course it has expanded very well on its own.
I'm thinking I may have gotten it in a pot at Home Depot and would like to ID it.
I think it is "Rocket City" but it is no longer dormant. It stays green all year and has just started blooming. It grows proliferations also.
I have other daylilies that were dormant for years (like 15) and this past year started staying green all year.
I confess there was a lot going on and my poor daylilies got no attention. Last year they did get fertilizer.
