Herbs, Native Plants, Wildflowers

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.

Regions:  Mountain, Piedmont, Coastal Plains 

Seasons of Interest:

  Blooms:  Early spring/spring            Nut/Fruit/Seed:  Spring

Wildlife Value:   This plant has little resistance to damage from deer.  Its flowers attract hummingbirds, butterflies, and bees

Blue phlox has hairy, sticky lance-shaped to elliptic opposite leaves (to 2" long). They can form large colonies over time as leafy shoots spread along the ground rooting at the nodes.
Blue phlox has loose clusters of slightly fragrant, tubular, lilac to rose to blue flowers (to 1.5" wide) with five, flat, wedge-shaped, notched, petal-like lobes that appear at the stem tips in spring. Its stamens are recessed. Stems are both hairy and sticky. The five petals are various shades of sky blue to violet.
Herbaceous perennial
Blue phlox is best grown in humusy, medium moisture, well-drained soil in part shade to full shade. It prefers rich, moist, organic soils. Also appreciates a light summer mulch which helps retain moisture and keep roots cool.
