That's disappointing to hear about all of the rust, especially on (as was mentioned on another thread) 'Marilyn Morss Johnson'. Some years ago I belonged to the "local" daylily club, where Marilyn was a member. She was a lovely lady, and I finally just got the plant this fall, to remember her by. I suppose I should expect to see it break out in rust not too long from now...
I really wish more hybridizers would work to incorporate some degree of rust resistance into their plants.
