Trailing, arching stems that root where they touch soil make these plants useful as groundcovers and bank covers. Shiny dark green, oval to oblong leaves. Lavender-blue, five-petaled, pinwheel-shaped flowers appear in leaf joints in early spring. Plant the larger species and its varieties 2–2 1/2 ft. apart, dwarf kinds 1/2 ft. apart.
When plantings mound up or are layered with old stems, shear or mow before new spring growth begins. Will grow in almost any soil. Compete successfully with surface tree roots.
