Abstract
A unique cultivar of Tall Phlox named ‘Opalescence’ characterized by vigorous, dense, upright, multi-stemmed, winter-hardy habit with dark-green, lanceolate leaves. Flowering begins in late-July and continuing for up to five weeks in cooler weather conditions, on heavily-branched peduncles and completely cover the top of the plant in peak season. Petals are light pink with darker pink eye. The new plant is able to withstand dry conditions once established, and the foliage stays clean and resists mildew. The new plant shows excellent powdery mildew resistance. The new plant is especially suitable for a cut flower, for the landscape as a potted plant and in the garden as a specimen or en masse.
