Widespread throughout the Sage Hills, long-leaf phlox presents a brilliant display of condensed pink or white flowers. The predominant flower color is pink but may vary to blue, lilac-purple, or white. The flower is distinctively five-lobed.

The large-flowered collomia grows from a single branching stem up to three feet tall with narrow leaves one to three inches long. The unusual peach- or salmon-colored blossoms with blue stamens at the center are arranged in many-flowered heads.
