A Native Creeping Phlox That Thrives Beyond the Sunny Rock Garden Sherwood Purple Creeping Phlox brings vivid spring color to partially shaded areas where traditional moss phlox may not perform well. This native selection forms a low, spreading mat of leafy stems beneath upright clusters of fragrant purple-blue flowers. The plant belongs to Phlox stolonifera, a creeping species native to Appalachian woodlands and streamside habitats. It is naturally adapted to growing beneath open tree canopies, along woodland edges, and in soil that remains moderately moist without becoming waterlogged. Sherwood Purple is sometimes sold as woodland phlox because it performs so well in woodland-style gardens. Botanically, however, it is a creeping phlox rather than the taller Phlox divaricata commonly known as woodland phlox. That distinction matters when choosing a plant for the landscape. Sherwood Purple creates a denser, lower groundcover and spreads through aboveground runners, making it an excellent choice for filling open soil beneath shrubs, lining shaded paths or softening the transition between a lawn and wooded area. Purple-Blue Flowers Rise Above a Dense Green Carpet During spring, upright flowering stems rise above the low foliage and carry loose clusters of rich purple-blue blossoms. Each flower has five rounded petals that extend from a narrow, tubular base, producing the familiar star-like form associated with phlox. The flowers are noticeably fragrant, adding another layer of interest when Sherwood Purple is planted near a woodland path, shaded sitting area, or garden entrance. Planting several together creates a stronger fragrance and a more visible sweep of purple color. Sherwood Purple typically flowers in April and May, depending on the climate and season. Its bloom time overlaps beautifully with spring bulbs, native sedges, foamflowers, Virginia bluebells, and early-blooming woodland shrubs. After flowering, the green foliage continues covering the soil. The low vegetative mat provides texture and helps prevent the area from looking bare once the spring flower display has finished. Vigorous Spreading Growth for Naturalizing and Weed-Suppressing Coverage Sherwood Purple spreads through stolons, which are aboveground stems that travel across the soil and form roots where they touch the ground. This growth habit allows a healthy plant to expand into a dense colony rather than remain in a single tight clump. The leafy groundcover usually remains only a few inches tall, while the flowering stems rise approximately 6 to 12 inches above the mat. Established plants can spread 12 to 24 inches or more, and vigorous colonies may expand by one to two feet during a favorable growing season. Use Sherwood Purple where spreading is a benefit: beneath deciduous trees, around the outer edges of shrubs, on partially shaded slopes, along woodland paths, or between larger shade perennials. Its shallow-rooted habit also allows it to grow over areas planted with spring bulbs. This is not an aggressive vine, but it should be given room to naturalize. Gardeners who prefer a sharply defined planting can trim wandering runners or lift rooted sections and replant them elsewhere. A Top-Performing Groundcover for Mid-Atlantic Shade Gardens Sherwood Purple has earned attention for more than its flower color. In regional trials, it developed a vigorous, dense mat of foliage and ranked among the strongest-performing selections of creeping phlox for shade. That vigor makes it particularly useful in Mid-Atlantic landscapes, where humid summers, variable rainfall, and competition from nearby tree roots can challenge less adaptable groundcovers. Once established, Sherwood Purple can recover quickly from small gaps or minor summer damage. Its flowers attract butterflies and hummingbirds in spring, while the dense foliage provides cover for the soil. The plant is generally considered tolerant of occasional deer browsing, although no groundcover should be treated as completely deer-proof. Powdery mildew may appear during humid summer weather, particularly where air circulation is poor. Minor mildew generally does not threaten an established colony, and trimming old flowering stems after bloom can encourage cleaner new growth. Partial Shade, Organic Soil, and Consistent Moisture Produce the Best Growth Plant Sherwood Purple in partial shade or filtered woodland light for the best balance of flowers and healthy foliage. Morning sun followed by afternoon shade is ideal. It can tolerate heavier shade, though flowering may be lighter, and it can tolerate more sun where the soil remains evenly moist. The preferred soil is rich in organic matter, moderately moist, and well-drained. Woodland soil improved with compost or leaf mold closely matches the conditions in which this native species naturally grows. Avoid locations where water remains standing around the crown. Water regularly during the first growing season while the shallow root system becomes established. Mature plants tolerate occasional dry periods, but prolonged heat and drought may cause foliage to decline or invite spider mites. After flowering, remove spent flower stems if a tidier appearance is desired. This light trimming can improve airflow and encourage a fresh layer of foliage. Avoid severely shearing the plant during hot summer weather, and allow the low, green vegetative stems to remain through winter where they are still green.
