Add crisp, clean color to your summer border with Phlox × 'Opening Act White' (Garden Phlox 'Opening Act White'). You get dense clusters of pure white flowers on a compact, upright plant that tops out around 18-20 inches tall, making it easy to tuck into small beds, front-of-border plantings, and containers.
Place it where you can enjoy the fragrance and the steady activity of pollinators. In full sun to partial shade, the blooms draw butterflies, hummingbirds, and other beneficial visitors through the heart of the growing season. The clumping habit keeps the plant looking tidy and makes it simple to pair with other perennials without crowding the design.
For best performance, plant in moist, well-drained soil and water during dry spells, especially while it establishes. Good air circulation helps keep foliage looking its best, so avoid packing plants too tightly; spacing near its mature width (about 18-20 inches) is a practical guideline. Mulching helps moderate soil moisture and keeps the root zone comfortable in summer heat.
After the main flush, you can shear or trim spent flower clusters to refresh the plant and encourage additional bloom. Cut stems back in late fall after frost and clean up old foliage to keep your planting area neat going into winter.
