Phlox diffusa (Spreading Phlox)

Mat Phlox, Spreading Phlox


Phlox diffusa (Spreading Phlox) is a mat-forming evergreen perennial boasting a profusion of small, star-shaped flowers with bright yellow anthers from late spring to late summer. Their color ranges from white to lavender to purple to pink. The blossoms are so profuse that they literally cover the evergreen foliage of narrow, needle-like, bright green leaves. Easy to grow, undemanding, Spreading Phlox is perfect for the sunny rock garden and water-wise gardens. This ground-hugging wildflower makes also an attractive groundcover.

  • Thrives in full sun in dry to moist, well-drained soils. Drought tolerant once established.
  • Excellent choice for rock gardens, cottage gardens, border edging or as a groundcover.
  • No serious pest or disease issues.
