Tiarella cordifolia (Foam Flower)
Michael's Opinion
One of our Canadian native plants that is frequently overlooked by locals. A perfect ground cover plant in moist shade in the woodland garden or as a foil with other moist, shade loving species. It is reliable, problem-free performer and should be seen more often in the garden.
