Periwinkle, especially Vinca Minor, is an evergreen ground cover that thrives in the shade, requires little to no maintenance and is Deer resistant... This would be a perfect bank cover behind our house, also maybe w/ another flower potted on our front porch!
Vinca Minor: I planted these in my front flower beds to get partial shade from overlying shrubbery. Be careful not to plant too much, and keep it tamed, as it grows like a weed. It does well in dry spells, and requires very little care other than thinning out the portions of growth that you don't want.
