Arggh, Larry, I clicked on your link, and that horrid picture popped up with the rust pustules RIGHT IN MY FACE!
It's too early in the morning to face such horrors...(for me, anyway...).
Last night I started working through the lists of plants currently present in the garden, doing a rust score estimation (in the absence of ATP decimal scores). It was surprising the number of plants that I had bought on the basis of rumored "stainless steel" resistance (as mentioned on one site or another) which scored over 2.0. 'J. T. Davis' got a score of 2.125, and I have to say that it's looking rather sketchy at the moment.
On the other hand, one plant that I was considering pitching for reasons other than rust (or leaf streak), scored pretty well with a 1.6. I've been of two minds on that plant for several years now. At one point I had yanked it out of its pot and left the whole clump to dry (and hopefully die.... the roots were packed so solidly the easiest thing to do seemed to be to let it decompose)... but I left it in the shade and that apparently gave it enough of an edge to survive. When I saw several months (a year?) later that it was
still alive, I told it "okay, since you want to live so much...". But just a few weeks ago I had made up my mind to toss it again. (The foliage always looks horrible early in the year... maybe with what is called "spring sickness"? And the flowers, while having a gorgeous color, have some form problems.) What's a girl to do?
