Summary

Phlox glaberrima, commonly known as Smooth Phlox, is a herbaceous perennial native to moist meadows, prairies, and low woods in the Southeastern USA. It typically grows to a height of 2-3 feet (0.6-0.9 meters) and a width of 2 feet (0.6 meters). This plant features lance-shaped leaves and produces clusters of fragrant flowers that can be pink, purple, red, or white, blooming profusely in late spring to early summer. The flowers are highly attractive to butterflies and hummingbirds, adding to the plant’s ornamental value.

Smooth Phlox is valued for its showy, fragrant flowers and its ability to attract pollinators. It is often used in borders, native plant gardens, and as part of pollinator-friendly landscaping. It prefers rich, moist, well-drained soils and can tolerate part shade, although it will bloom most prolifically in full sun. While generally easy to maintain, it can be susceptible to powdery mildew, especially in crowded conditions or poor air circulation. To prevent this, good spacing and site selection are important.CC BY-SA 4.0
