Phlox speciosa subsp. occidentalis, commonly known as Showy Phlox, is a perennial herb or subshrub that is native to open woodlands, forest edges, and grassy slopes in the Pacific Northwest of the United States. It typically grows to a height of 2 feet (0.6 meters) and a width of 0.4-1 feet (0.1-0.3 meters). Showy Phlox has a clumping form with lance-shaped leaves and produces clusters of vibrant pink to purplish flowers that bloom profusely in the spring and early summer, attracting pollinators such as butterflies and hummingbirds.

This plant is valued for its ornamental flowers and its ability to thrive with minimal care, making it suitable for rock gardens, borders, and native plant gardens. Showy Phlox prefers full sun to part shade and requires well-drained soils; it is drought-tolerant once established. While it is generally disease-resistant, powdery mildew can be a problem in humid conditions. It is not known for aggressive roots or invasiveness. To maintain vigor, divide clumps every few years and remove any dead foliage to prevent disease.CC BY-SA 4.0
