Phlox maculata

Phlox maculata, commonly called meadow phlox, as well as wild sweet William and marsh phlox, is a species of flowering plant in the family Polemoniaceae, native the eastern United States and introduced to eastern Canada. It is a perennial. Growing to 2–3 ft (61–91 cm), this erect, clump-forming herbaceous perennial produces clusters of fragrant, deep pink flowers in summer. The stiff stems are spotted red, hence the Latin specific epithet maculata. It prefers damp, well-drained soil in full sun. It is less prone to powdery mildew than the related Phlox paniculata. The following cultivars have received the Royal Horticultural Society's Award of Garden Merit: 'Alpha' (lilac) 'Natascha' (pink and white) 'Omega' (white with a red eye)...read more on Wikipedia.
