Classic garden plants like peonies give the garden a touch of nostalgia and charm. Years of popularity have been fueled by their fragrant blossoms and lush foliage, and with the recent rebirth in breeding, they will only get better. Peonies are easy to grow and can be used in a variety of settings, such as bulk plantings, individual specimens, or hedges. You can extend the length of your flowers by up to 6 weeks by combining early, midseason, and late blooming cultivars.
