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 perennialherb 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 a centimeter 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 a centimeter long and a flat five-lobed corolla.
