Hollyhock, Annual or Perennial

It’s that time of the year when the hollyhock are beginning to bloom, but are they a perennial or an annual plant?

Hollyhocks (Alcea rosea) tower majestically at the back of a flowerbed on 4- to 5-foot stalks that bear 3- to 6-inch flowers in shades of white to pink to purple, and even yellow hues. Each flower lasts only a few days, but the season of bloom can be up to three weeks here in Minnesota. Hollyhocks require well-drained soil and full sun. While they are sometimes listed as both annuals and perennials, hollyhocks' life cycle is a bit more complex than those categories indicate.
