Abstract
A new and unique hybrid cultivar of garden phlox named Phlox ‘Opening Act Pink-a-Dot’ multi-stemmed, medium upright height, slowly-spreading habit with clean, medium-green, glossy, lanceolate leaves with exceptional powdery mildew resistance. Foliage is thick and leathery on stiff stems. Flowers are near white with deep pink eye resembling a star, produced on branched peduncles and nearly cover the top of the plant beginning early summer, about two weeks prior typical Phlox paniculata cultivars and continuing for about five weeks. ‘Opening Act Pink-a-Dot’ is especially suitable as a potted plant, for the garden, for attracting hummingbirds and butterflies, and for cut flower arrangements.
