I am in PA and zone should be 7.

Closer views needed.

consider a beech tree

If you can, go out under each tree and see if you can find several leaves that you can photograph or even just the overall leaf litter. In combination with the overall photos, that may be enough for ID of photos 1 and 3, though it may not since fallen leaves do blow around.

Photo 2 looks like a dogwood, either the native Cornus florida or Cornus kousa, an Asian dogwood. C. florida blooms before the leaves emerge, while Kousa dogwood blooms along with the leaves. Look at photos and see if they look familiar.

In photo 3 are you asking about the evergreen near the bottom of the photo, which appears to be a spruce, or are you asking about the large peachy-colored tree in the background?

Thank you so much. I waited too long. There are no leaves. I will have to come back in spring time with close-up photos of 1 and 3.

NHBabs - Ref. photo 2, I looked at photos and I think it is Japanese Kousa Dogwood as I have seen red fruit before the fall of leaves.

In photo 3, I am asking about the large peachy-colored tree but again I will have to come back as there are no leaves for details.

Thanks again!

Are there really no leaves at all on the ground beneath the trees? Not one?

Go to tree forum and ask for suggestions of what to plant, You will get many good ideas and have winter to consider them.

That's a great idea. Thank you!
