Garden phlox (Phlox paniculata) is a clump-forming perennial 2-4 ft tall that produces fragrant, dense summer-to-early-fall panicles in pinks, reds, purples and whites, attracting butterflies and hummingbirds and making excellent borders or cut flowers in Willamette Valley gardens. Plant in full sun to part shade in rich, evenly moist, well-drained soil, space for good air circulation and divide every 3-4 years to reduce powdery mildew and maintain vigorous growth.
