I have had Lilting Belle for 13 years and will probably always have it, as it is a later blooming daylily. It forms a very nice clump fairly quickly. Blooms do well in the hot sun. Stats are pretty much accurate in my zone. It is fertile but for me has not produced a whole lot of seeds. Pods will often abort but I still use it and have gotten some nice seedlings from it. For me, it's a keeper.
