Periwinkle is a perennial with evergreen leaves and pretty, blue, or violet flowers in the spring.
It is tolerant of drought, shade, deer, and rocky, clay or sandy soils. A very tough plant!
Vinca spreads rapidly by rooting at the stem joints.
So although it is an attractive ground cover, it can be difficult to contain once established and can take over even in dry, total shade.
