Phlox divaricata is a spreading woodland phlox known for its soft mounding habit and fragrant spring flowers in varying shades of blue and lavender. The slightly notched petals and sweet scent make it a seasonal highlight in shady or semi shaded landscapes. Its semi evergreen foliage provides low ground cover into summer and its early blooms serve as a key nectar source after winter dormancy.
