Why We Love It:
This beautiful woodland phlox brings soft color and fragrance to shaded garden spaces where many flowering perennials struggle. Its lavender-blue blooms seem to float above lush green foliage in spring, creating a natural woodland look that feels relaxed and effortless. As it slowly spreads into colonies, it forms beautiful drifts that attract hummingbirds and butterflies while brightening shady borders and woodland gardens.

Additional Info:
Also known as Wild Sweet William, this eastern North American native thrives in rich, moisture-retentive soils with consistent moisture and cooler root conditions. A light mulch helps maintain soil moisture and protect roots during warmer weather. Plants may go dormant during prolonged drought but typically recover once moisture returns. Deer resistant and adaptable to shade and heavier soils.
