Way back when, in 2006, there was no doubt whatsoever that it was rust ravaging through the garden. That was when 'Cameroons' and 'Green Dolphin Street' were hit; they were near 'Icy Lemon', which was an absolute screaming horror of a rust bucket. (And yes, I did the tissue test then...)
The plants right now that are showing "rust" are ones that get hit with irrigation spray, so in at least some of these plants, I am pretty sure it is rust. (I had rust break out on incoming plants, and I think I must have spread it around.)
I guess I get out there with the tissue tomorrow... just to be sure...
(While I have been tossing lots of plants, there does come a time when I struggle with myself when a plant with a particularly beautiful flower, or with some combination of desirable traits, gets hit. Then comes the question: how much rust grief am I willing to put up with, to keep this plant? (Especially given that I don't do the fungicide spray thing...))
Sigh...
