Last week, with evening sunshine glinting off the riffled waters of Lake Superior's North Shore, and a surprisingly warm breeze wafting over the spit of wave-washed bedrock, a flower caught my eye. Rock-hopping over, I discovered the pink petals and yellow centers I'd been looking for. Notches in each of the five petals gave them a lovely heart shape. At the base of the flower's wiry stem was a little rosette of bright green leaves with wavy edges. This flower was one of dozens all sprouting from the cushion of moss in a little bedrock nook. Besides the Bird's-eye Primrose, quite a diversity of plants crowded together in this island of habitat surrounded by a sea of bedrock.
