Seedfork said:'Buttered Popcorn' with a rust resistance rating of 1.3 was one of the first daylilies I ever ordered online. The main reason for ordering it along with the others in that order was rust resistance. So naturally, I have been very disappointed that here in my garden 'Buttered Popcorn' has been one of my most rust prone daylilies for the past two seasons. The rust was so bad that at one point there were no leaves left on the plant. It had just recently seemed to recover and now has decent looking foliage. Because of the rust the plant has naturally suffered, it did bloom, and rebloom but it has been noticeably set back a few times this season. If not for the rust I do feel this plant would have thrived and been much more developed than it currently is. I love the color, and if I can find a viable way of controlling the rust it will stay in my garden, but if not then it will have to go.

My experience has been exactly the same. I ordered Buttered Popcorn in the spring because of the rust resistance rating, and at first, I was delighted with it. It bloomed profusely, and the blooms had great substance and really stood out. However, it has developed rust multiple times this past summer, and I am thinking it will have to go. I may give it one more summer. I would be interested, Larry, to find out if yours has done any better since you wrote the above.

My guess is that since Buttered Popcorn had been assigned that excellent rating, it has been exposed to different strains of rust.
