Hood’s Phlox (Phlox hoodii Richardson) is a highly variable, widespread species found in Western North America from Alaska to Northern Mexico on the west to Manitoba, Nebraska, and New Mexico on the East. It is a common constituent of the sagebrush community, and is one of the first blooming plants in the spring after the snow melts. It is not found along the coasts. In Washington, it is found east of the Cascades.

Phlox hoodii is also referred to as Carpet Phlox, Moss Phlox, and Spiny Phlox among other names.

The morphology of this species is highly variable with several recognized varieties. I am not sure which variety this one is, but it is one of the mat forming ones growing from a deep tap root. There is at least one variety that is more erect.
