Coming *very* late to this thread... (I'll spare you the excuses...)
'Spacecoast Tiny Perfection' is rust prone?! I asked for it as a gift plant this spring, because I thought it was resistant!
Aphids and spider mites do THAT kind of damage? DANG.... (I may have thrown out some plants I thought had rust... but maybe it wasn't rust after all?)
I have more plants that right now look like they have rust... I was getting ready to either cut them back, or else dig and destroy them... I guess I'll have to look closer, and do the tissue test, before I toss any more plants...
THANKS for the warning (and the link with comparative pictures)!
As for plants that at one time had rust, but not since... I've seen that with 'Cameroons' and 'Green Dolphin Street'. I'm guessing that the weather was a factor there... the year they got rust, we had a lot of rain in the spring. It's been pretty dry here in CA the past few years.
