If I recall you live in New England. I was going to suggest a few then re-read your post and this
stood out. I encourage growing native and naturalized plants. Look at solar exposure, soil, how much (or little) energy you wish to expend. I was going to name a few then remembered that some years ago someone sent me a link to this nursery. I went there and they have a great list of shrubs, grasses, trees, and flowers. Check it out!
