Foamflower

Tiarella cordifolia, or foamflower (sometimes "Allegheny foamflower"), is a groundcover perennial native to upper North America (endangered in Wisconsin) that has been cultivated and hybridized. A popular variation, shown here, is the "Brandywine" which features darker, even burgundy veining amidst bright green grapevine-shaped leaves with an interesting texture.

This native was able to thrive in a dark, shady area where I'd had trouble getting anything to grow, and looks great along a path or pond edge. For about 6-8 weeks in spring it shoots up a racene, a tall stalk of tiny, fluffy white flowers, hence the name. It spreads slowly but surely over time. During the season the leaves become darker, and bronze in the fall if you don't let your patch dry out in August heat.
