Vinca minor

Evergreen, low-growing, perennial, groundcover with dense green, spreading foliage. From spring and throughout the year masses of bright blue star-like flowers appear. A great hardy ground cover that continually spreads. As the arching stems make contact with the soil they set roots, so best to ensure that the plant is confined to your property and it doesn't escape. Ideal for a shady areas and under story plantings.
