'Opening Act White' Phlox

Opening Act White is an early-flowering hybrid garden phlox with pure white flowers from early summer through midsummer and occasional rebloom into early fall. It grows about 18–20 inches tall and wide, spreading gradually by stolons. The [Walters Gardens plant profile](https://www.waltersgardens.com/variety.php?ID=PHLOW) identifies it in the Opening Act series and notes glossy foliage with resistance to powdery mildew and disease. Choose a sunny, well-ventilated spot; part shade is tolerated, though full sun favors flowering. Average to fertile soil and regular moisture suit this perennial. The flowers brighten a border, container, cut-flower planting, or massed display, while offering forage for bees, butterflies, and hummingbirds. ## Maintenance Water consistently but avoid keeping the root zone saturated. Water near the soil surface rather than over the foliage, and give stems enough room for air movement. Remove spent flower stems to tidy the clump and support continued flowering; avoid crowding it with plants that block sunlight or airflow.
