Considered a biennial Hollyhock will only flower for one full growing season. The best way we find to grow hollyhock is to sow these directly in your garden from late summer until at least two weeks before your first frost in early fall. Hollyhock will not germinate when temps are 60 or below and need several days of temps in the 70's to germinate.
