Polymerous,
I would be very interested in a list of your daylilies that are not listed in the database as rust resistant but that you find have not been susceptible to rust in your garden.
I am trying my best to limit my "Want list" to daylilies that are good "clumpers" and are listed as being rust resistant, I have twenty five on my list at present none of them are the expensive new ones, but that is fine with me.
