Thank you for your question, Betsy. Although we are reluctant to diagnose a problem without photos, your description is of the only disease in our area of this species. https://pnwhandbooks.org/plantdisease/host-disease/hollyhock-alcea-rosea-rust
Those fungicides marked "H" are available to homeowners, but need to be applied before the fungus takes hold. I hope this helps. Good luck!
