The rock formations along the shore of Maine continue to fascinate me. This spring I looked more closely and found nature details everywhere. Violets and ground ivy tucked in around the rocks, or on the edge of flower beds nurtured by last year’s acorn husks. The ground ivy is not native to America but was used for food and medicine in Europe, and may have come to Maine with early settlers. As a result, it has many common names. Field balm makes sense but, gill-over-the-ground still puzzles me.
