The first photo is a plant called Campanula. It's common name is BellFlower, and there are a number of varieties - most are blue or white.
The white-blossomed plant with the interesting leaves is a wild Aster. They are very hearty and will survive even the most punishing winters. They make a great addition to a cut-flower bouquet.
The very last one - shown in the separate post - is indeed a wild orchid. I used to have them at my old house - they're another amazingly hearty variety.
The one under the Aster could possibly be a wild Columbine, based upon the leaves, but I can't be sure without a closer view of the blossom. Any chance you got a close-up?
