Provincetown is on Cape Cod, not in Boston.

Could you list the plants/herbs/flowers in this garden?

The very first plant at the "V" beginning of the path on the right looks like a perennial Lamb's Ear. The plant behind it with lavender flowers spreading out is Cat Mint. Under the first window looks like Russian Sage. On the left side the first few plants I'm unable to see clearly. But you can see a small Rose bush with pale, possibly cream colored flowers. Next to that are tall pink perennials with fern like leaves called Cosmos. Though difficult to clearly see the bright orange flowers may be lilies, possibly tiger lilies. Hope this helps a bit. It's a very pretty flower garden though needs some pruning.

Lovely garden

Looks to me like the pink flowers on the left are cosmos, behind the creamy-colored roses. The small lavender blooms to the right of them are verbena bonariensis (tall verbena, a self-seeding perennial). The dark green leaves in front of the verbena look like kale to me.
