Comment:

Phlox divaricata, commonly called woodland phlox, is a spreading, native wildflower which forms mats of foliage with stems typically reaching 12-15" tall. As the common name suggests, this is a woodland species which occurs in rich woods, fields and along streams.  

Some uses in the garden include rock gardens, border fronts, wild gardens, native plant gardens or naturalized areas. It is also an effective, shallow-rooted cover for early spring bulbs.
