Phlox douglasii (Douglas' phlox) is a native California perennial in the Polemoniaceae family, recognized by cushion-like habit with glandular-hairy herbage throughout.

Douglas' phlox is a California native perennial found in central Sierra Nevada and Great Basin bioregions in dry sagebrush scrub and juniper woodland at elevations of 1,500 to 2,000 meters. Flowering from April to May, this plant produces pink, pale lavender, or white flowers in small terminal clusters of 1 to 3 blossoms. Growing as a compact, mat-like or cushion-like plant with glandular-hairy stems, it forms dense low-growing colonies. Its leaves are small and sharp-tipped, lance-linear in shape, measuring 4 to 8 millimeters long. The flower's pale pink to white corolla tube extends approximately 10 millimeters, creating a delicate and intricate bloom.
