Lamium is one of the best choices for a tough yet showy perennial groundcover. This British selection forms a spreading patch of small leaves, brightly marbled with light and dark green, chartreuse and silver. Clusters of mauve-pink flowers appear in spring then continue on and off until fall. Fairly tolerant of dry shade, once established. Trim or mow back in late winter. Stems will root into the ground where they touch, and any new plants that form can be easily moved in spring or fall. Also easily divided. Evergreen.
