Thanks Maryl. I know all about erratic winter weather - and erratic weather in the rest of the seasons too
. I had not heard that going dormant in the summer affected rust. I was just wondering because I haven't seen it here. I just had a few that I allowed to go deeply into that dormancy and a few had no green left. When I cleaned the foliage off and started keeping them moist, they grew quite well. To all appearances they went just as dormant as those that disappear in the winter months. I keep watching for rust because I think it should manage to survive here, but so far every time I've thought it might be showing up nothing has materialized. I think your normally hot, windy summer conditions with low humidity probably match my conditions better than most people. If rust survived weeks of triple digits in your location, then I've probably just been lucky. Thanks again.
