Phlox pulvinata

Phlox pulvinata is a species of phlox known by the common name cushion phlox. It is native to the western United States where it grows in mountain and plateau habitat, in rocky subalpine and alpine climates, including exposed tundra habitat. It is a perennial herb taking a flat, dense, cushionlike form on the ground. Its very short stems are lined with hair-fringed lance-shaped leaves each no more than 1 cm long. The plant is among the first to flower in the spring in many areas. It blooms densely, forming carpets of flowers. Each white to pale pink flower has a tubular throat up to 1 cm long and a flat five-lobed corolla.
