Sorry to hear about your phloxes "rusting", Betty. The hollyhock is another plant that has a rust problem. I've been encouraging my hollyhocks to self-seed, in the hope that rust-resistant plants will be strongest and form the most seeds, so most of the offspring will inherit rust-resistance. The hollyhocks started off at the back of the flower border, then migrated forwards through the bed, and now they are growing in the driveway gravel at the fore.
