Picture of Rose Campion Flowers

Once established, rose campion flowers (Lychnis coronaria) multiply and spread beyond their original bounds. Even when they act more like annuals than perennials, they will re-seed readily. Rose campion flowers can be grown in planting zones 4-8. They reach a height of 2'-3'. More accurately a "rose magenta" color, the deep pink rose campion flowers bloom on a fuzzy, silvery stalk that is appealing in its own right.
