Since 1990 members of the Perennial Plant Association (PPA) have chosen a Perennial Plant of the Year™. To date 24 great plants have been named. In parallel, the Chelsea Flower Show in England has designated a plant in each of its 100 years. Each decade the Flower Show selects the best plant, which has included many trees, shrubs, and annual plants.
Each decade’s winner was then placed on a ballot to pick the “Plant of the Centenary”. Geranium Rozanne (‘Gerwat’), selected PPA Perennial Plant of the Year in 2008, was designated.
Among the ten contestants in the Chelsea list was another PPA favorite Palace Purple coralbells (Heuchera ‘Palace Purple’), the 1991 Perennial Plant of the Year™. Palace Purple is still a popular heuchera in garden centers. ‘Palace Purple’ was tapped by Chelsea to represent the decade from 1983-1992.
