That's interesting to hear about your Dutch Yellow Truffle Pam. I had my first rust outbreak last year when I brought in some new daylilies from a southern grower. It caught me by surprise and it was awhile before I believed what I was seeing. Anyway Dutch Yellow Truffle was right in amongst all the rusters and never got so much as a spot on it before I got it out of harms way. I was listing my rusters/non-rusters on the database here, but don't know if I got them all done. DYT did great for me in the rust department, and it's one of the most consistantly formed peony type doubles I've seen. Both sunfast and colorfast here too. Very good over all daylily IMO.......Maryl
