Picture of a wildflower meadow from Cape Rosier, an area along the Maine coast perhaps best known as the location for the last homestead of Helen and Scott Nearing. This meadow contains flag (the blue), ragged robin (pink), and hawkweed (the yellow and bit of orange).

I frequently encounter two kinds of baneberry (Actaea) on my walks through shady wooded areas of New England (U.S.): red baneberry (picture) and white. The white type is also called "doll's eyes," because its berry is white with a black "pupil" in the middle.

perennial geraniums - cranesbill - wild geraniums... These are ground cover plants. They grow all over the sand dunes along parts of the Northumberland coast in England UK & are a wonderful sight. They're at home in a windy garden & flower profusely over a long period. You can buy the natural colour pictured, or shades of pink.
