'Flower Power' lives up to its name! Mounds of delicately scented white flowers top glossy green foliage. The plant grows to 36 to 40 inches tall and blooms from May through August. As an additional treat, the flowers are flecked with pink in the cooler hours of morning and evening. 'Flower Power' is a very easy-to-maintain perennial and is relatively resistant to mildew. Grow it in full sun in medium to moist soil in a border, wildflower garden, or a container where it will attract birds and butterflies.
