Phlox in bloom is a spectacle—masses of small, star-shaped flowers blanketing plants. Two main types: spring-blooming creeping phlox (groundcover) and summer-blooming tall garden phlox.
A phlox for almost any situation. Creeping phlox for rock gardens, woodland plantings. Tall phlox brightens back of border with exuberant early summer flowers. Tall phlox susceptible to powdery mildew in hot, humid summers—choose resistant varieties.
Moist, well-drained soil. Some types prefer full sun, others thrive in shade.
Spring, space 1–2 feet. Loosen soil 12–15 inches, add 2–4 inches compost. Plant at container depth, water thoroughly.
Spring: thin compost + 2-inch mulch. Water if rainfall <1 inch/week. Cut back old flower stems to encourage rebloom. Divide tall garden phlox every 2–3 years for vigor and disease reduction. After killing frost, cut tall phlox stems to 1–2 inches.
