A flat, mat-forming perennial with flowering branches less than 4 in. high. The thick, round leaves are dark green, sometimes red-tinged. A matted plant with a woody base and stems, opposite, crowded leaves, and blue-lavender, bilaterally symmetrical flowers clustered on short erect stems. The short flowering branches usually bear 2-4 blue-purple to rose-purple flowers that seem unusually large for such a matted plant.

When in full flower, this species forms spectacular lavender mats. Plants in the southern part of the range have toothless leaves; to the north, toothed leaves are common.
