Bowles Periwinkle
Vinca minor
Small blue-lavender flowers against leathery dark green leaves in spring, a tough and adaptable ground cover that earns its keep across zones 4 to 9.
Common periwinkle is the more restrained of the two Vinca species in cultivation, with narrower leaves that are thicker in texture and flowers that are smaller than those of Vinca major. It spreads at the nodes, forming a low mat three to six inches high, and tolerates a wide range of conditions from full sun to nearly full shade. Bumblebees work the flowers in spring. The cultivar selection includes variegated and gold-leaved forms for gardeners wanting more than just the standard deep green.
The catch, as with its larger relative, is a tendency to spread beyond where it was planted. Vine stem canker can flatten large patches without warning, and the plant has made invasive species lists across multiple states. In spite of this, its hardiness range down to zone 4, its deer resistance, and its tolerance for dry shade make it a practical choice in difficult spots where more desirable ground covers struggle. Weigh the tradeoffs honestly before planting near natural areas or stream edges.
