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. Loose clusters of slightly fragrant, tubular, lilac to rose to blue flowers (to 1.5" wide) with five, flat, notched, petal-like lobes that appear at the stem tips in spring. Stems are both hairy and sticky. Lance-shaped to elliptic leaves (to 2" long). Can form large colonies over time as leafy shoots spread along the ground rooting at the nodes.
Powdery mildew can be a serious problem. Cutting back stems after flowering helps combat mildew. Spider mites can also be a problem, particularly in hot, dry conditions. Watch out for rabbits.
Rock gardens, border fronts, wild gardens, native plant gardens or naturalized areas. Also an effective, shallow-rooted cover for early spring bulbs.
