Probably a hybrid between P. oppositifolia and P. myrtifolia. Grows to 3–5 ft. tall and wide; usually bare at the base. Grayish green, oval to lance-shaped leaves to 1 in. long. Blooms nonstop from midsummer to fall, producing flowers in a bright, vivid purplish pink that combines well with blue shades and white.
