Also known as Myrtle. This is probably the most popular evergreen groundcover, forming a dense mat of glossy dark green leaves, studded with bright blue flowers in spring. Very shade tolerant, the leaves will sometimes scorch in too much sun. Tolerates dry shade once plants are established. Stems root into the ground readily, and the new plants that form may be easily moved to a new location in spring or early fall. Mowing the patch low after blooming every couple of years will help to keep it thick and weed resistant. Plant 4 to 10 plants per square yard.
