Vinca minor
A refined, fine-textured evergreen ground cover that forms a dense mat 3 to 6 inches tall, spreading by trailing, rooting stems to 18 inches or more. It favors part to full shade and moderate water, tolerating a range of soils once established. Small, glossy dark green leaves carry lavender-blue flowers in spring, with scattered rebloom. A dependable lawn substitute and weed-suppressing carpet for shaded slopes, parkways, borders, and large beds under trees where a tidier habit than the larger periwinkle is preferred.
