Waldsteinia fragaroides: flowers

Waldsteinia fragaroides, known in English as "barren strawberry" and in French as waldsteinie faux-fraisier, is a low-growing perennial native to eastern North America. Its three-part leaves and five-petalled yellow flowers are reminiscent of strawberry leaves and flowers (Fragaria spp.), but the flowers are yellow and it does not bear edible fruit.

When I was growing up in eastern Ontario, barren strawberries carpeted the forest floor; i.e. they can make a good groundcover for shade in the right conditions. I bought this plant at the North American Native Plant Society plant sale last weekend.
