Hi, Well once hollyhocks complete their life cycle, they begin to die. Hollyhocks are biennial, this means they grow foliage the first year, bloom the second and then die. They do not come back every year. However, they often seem like perennials because they self sow thoroughly so there are always plants growing in the bed. They generally die back from bottom to top so I think your plants are doing what comes naturally.
