Phlox hoodii, the spiny phlox or carpet phlox, is a species of phlox. It is a plant of western North America, where it is a common flower in sagebrush country, mostly growing in dry lithosol habitats.[1] It is among the first plants to bloom in spring, after the snow has melted. Its distribution extends from Alaska to Arizona.[2] There are many subspecies.
This perennial herb is variable in morphology, but usually forms a tight mat or loose clump on the ground.[2] The short stems emerge from a woody taproot and caudex unit and the plant form is no more than 13cm (05inches) tall.[2] The abundant tiny, sharp-pointed leaves are oppositely arranged and barely exceed 1frac=3NaNfrac=3 long. The herbage is hairy in texture, the hairs short to long, woolly to cobwebby.[2] The appearance of the plant is almost mosslike until blooming.[3] The inflorescence is a solitary flower in shades of white, pink, or blue.[2] It has a tubular throat about 1frac=3NaNfrac=3 long spreading into a flat five-lobed corolla.
