Hollyhock rust is common on hollyhocks and the symptoms you describe fit the problem exactly. Early spring treatment with fungicides containing chlorothalonil, sulfur, or neem oil can help prevent the disease but there's no cure once your plant is completely involved. I'd prune it down to ground level. When new growth emerges, start your fungicide spray program (according to label directions) to keep the growth disease free. Good luck with your hollyhocks!
