I don't know if it's native, but Sweet Woodruff grows like gangbusters. It grows in sun or shade and is deer resistant. I bought a very small pot of it in the spring of 2013. I planted the clump beside a bleeding heart. Late that summer, I divided it into small sections and placed it all around the base of the bleeding heart plant. A year later it had doubled in size in the area where it was planted.

First pic is when I bought it 2013. Second pics are a year later June 2014. In May/June it's covered with white flowers. Stays green all summer if kept watered. This year it SPREAD to about twice the size it was in 2014. Haven't gotten around to taking a photo, but it's just starting to bloom now.
