Yes Im too get lots of rust but it does not seem to affect the quality of the flowers but like Spritz I to remove the affected leaves.

There are some chemical treatments, but nothing much works once the leaves start curling. Next year, inspect the undersides of the leaves at least weekly, so you can hit it with sulfur spray before it gets too bad!

It's Hollyhock rust, I'd imagine - mine get it every year, and I remove the leaves as they fall and burn them. I'm sure it won't affect the frogs, but it is unsightly. I'm not aware of any cure.
