I am in zone 6, eastern PA. Any ideas, help, suggestions would be much appreciated. Thanks!

In addition to the far left tree, I would keep at least one boxwood, or replace the shrubs with at least one other evergreen. I think you are going to want something for winter interest.

There is not a lot of room, but some hakone grass and small hostas or heucheras could fit in there with all the shrubs, and you could fill with annuals for color.

Nice job on the wall! This will be a nice entry garden. Let us know what you end up doing.

I would take a pic with me when shopping to make sure flowers/foliage are pleasing against the particular shade of brick, probably try to stick with one other color of flower besides white. (White = no brainer there to me.) Variegated foliage! Maybe a couple shepherd hooks to hang baskets of pretty trailing leaves in the summer. Not really at the plant-selecting stage if you're still unsure about shrubs, again IMHO. Sounds like you want mostly a do it & forget it approach, so being happy later depends on the overall structure first. Don't get yourself into an unnecessary yearly pruning regime (which you already have) if you replace the shrubs with others, get plants that are the right size when mature, not just the day they're bought, or "can be kept to X size." Keeping your house from being eaten by shrubs is not my idea of fun.

Absolutely LOVE the curved wall! Is there enough sun for creeping phlox at the edge? Not too much, 3 would be perfect to me. I would like flowers there that have low foliage with taller "see through" flowers that you can see from inside but not really blocking the view, forms like Brunnera, Thalictrum (maybe too tall,) Myosotis, Hosta.

And thank you for nice comments on the wall.

You said, "I am trying to stay away from flowers since I have weed barrier all throughout." I am going to gently suggest that regardless of what you plant there, first get rid of the weed block based on my experience with it. (You can also do a search in various forums for weed block fabric to get other perspectives.) Weed seeds will blow in from above, sprout, and root into the weed block, and whatever you plant may root into it from below. We used it under some evergreens when we first started gardening, and by the time we realized it was a problem it was virtually impossible to get rid of. It does have its place under walkways and behind rock walls, but not in a garden. In addition to not preventing weeds, it also prevents the normal process of organic matter breaking down and improving the texture and nutrients in the soil.
