Nice evergreen groundcover, with a bit of fall color to boot. I have this growing between rocks around my small pond, does quite well.

Has toothed, mid-dark green leaves divided into 3 square shaped leaflets. Bears stalks of small, white, 4 petalled flowers. Very occasionally you may find a pink flowered plant.

Flowers between April-July

Likes moist, drained, leafy soil in shade or partial shade. Nice little woodland garden plant.
