The bike path was once a coal-hauling railroad right-of-way. Consequently, several areas on the edge of the trail are sparce and predominately coal waste, cinders and slag ballast. It is in these particular "desert" areas that Lamb's Ear and Wild Strawberry flourish. I like to imagine it's the extra carbon or iron that makes them grow so well, but I really don't know.
Postulate: Some good things may even come from things we lay to waste.
