Phlox paniculata, commonly known as garden phlox, is an upright perennial that grows in a clump to 2-4' tall and to 2-3' wide on stiff stems clad with conspicuously veined, opposite, pointed, elliptic, deep green leaves. Fragrant, tubular, pink-purple to white florets are densely packed in large, tiered, domed terminal clusters over a long July to September bloom period. Each individual floret has a long corolla tube and five flat petal-like lobes. Butterflies love the flowers.
Grow in moderately fertile, medium moisture, well-drained soil in full sun to part shade. Best in full sun. Prefers rich, moist, organic soils. Also prefers moderate summer temperatures over the heat and humidity. Needs good air circulation (space well and thin out stems as needed) to help combat potential powdery mildew problems. Intolerant of drought and needs to be watered in dry spells. Avoid overhead watering however. Appreciates a summer mulch which helps keep the root zone cool. For winter, cut plants to the ground and remove from the garden plus clean up all plant areas in order to minimize possible powdery mildew infection for the following growing season. Remove faded flower panicles to prolong bloom period and to prevent unwanted self-seeding (cultivars generally do not come true from seed).
