SonoveShakespeare said:I just call them double ditch lilies. They're the hardiest daylily out of all the ones I have especially to diseases and crown rot (you can't ever kill them). Surprisingly, I've never had any double or regular ditch lily get Daylily Rust. I don't think they're prone to get DL rust.

'Kwanso' (as H. fulva var. kwanso) is listed as susceptible in Japan. But since you're in Zone 5 presumably you only get rust if you bring it in on new plants because it should not survive the winter.
