The large Hydrangea-like flower clusters of Summer Phlox create a spectacular show in the summer border. Sweetly fragrant as well, the flowers waft their scent over quite a distance. This tall selection has clear white heads, over a clump of dark green foliage. It is one of the most powdery mildew-resistant varieties to date. Summer Phlox are superb for cutting, and may even attract passing butterflies. Remove faded flowers to encourage a second bloom. Clumps are easily divided in early spring. May need staking. Selected as the Perennial Plant of the Year for 2002.
