What is this?

The plant you’re inquiring about is Cardamine trifolia, commonly know as lady’s smock or 3-leaved cuckooflower. This is an attractive, well-behaved evergreen ground cover, about six-inches tall and covering up to twenty-four inches across. The dark green leaves with a purple reverse are three-parted. The white flowers are borne in early spring. Flowering is brief and they rarely set seed.

Cardamine trifolia prefers shade to part shade, but will tolerate sun if kept moist, and likes humus-rich soil. It’s a good companion plant for many plants in the spring and shade garden and especially looks good under Lace Leaf Japanese maples as there are few plants that like these conditions.
