Geum macrophyllum

This Geum grows in moutain meadows, along trails, springs and seeps at higher elevations in California. In Canada and the rest of the northern hemisphere Big Leaf Avens grows all the way down to sea level. This native can compete with a lawn, to become almost a lawn, just with big leaves. Needs part sun to sun and regular water, like a lawn. Plant a few into a shady, moist flowerbed and you get yellow potentilla like flowers rising above nearly flat leaves.
