Phlox caespitosa, commonly known as Tufted Phlox, is a perennial herb native to alpine regions and subalpine meadows of Western North America, including the Rocky Mountains and the Cascades. It is adapted to high elevations and often found in rocky, well-drained sites. This species typically forms dense mats reaching 0.3-0.5 feet (0.09-0.15 meters) in height and spreading 0.5-1 feet (0.15-0.3 meters) wide. Tufted Phlox is characterized by its cushion-like growth habit and masses of vibrant pink to purple flowers that bloom profusely in the spring, creating a carpet-like appearance. The flowers are highly attractive to pollinators such as butterflies and bees.

Tufted Phlox is valued for its showy spring flowers and its ability to form a ground cover, making it ideal for rock gardens, alpine gardens, and as a border plant in garden settings. It is drought-tolerant once established and requires minimal maintenance, thriving in full sun to part shade. It prefers well-drained soils, including clay, loam, or sandy types, and benefits from occasional watering during prolonged dry periods. While generally disease-resistant, Phlox caespitosa can be susceptible to powdery mildew in humid conditions. It is not known for aggressive roots or significant pest problems.CC BY-SA 4.0
