Growing Hollyhocks - stock photo

A classic cottage garden staple, hollyhocks (Alcea rosea) bloom mid-summer with numerous flowers on tall spikes. Many of the most common varieties are biennials, meaning they complete their lifecycle over 2 years. The first year is spent growing foliage and storing energy. In the second year, the stalks shoot up, flowers bloom and seeds form. However, there are also many varieties that behave like short-lived perennials and will flower in their first year when planted early enough in spring or started indoors in winter.
