You have two huge trees that are not symmetrical. Among other things, the right corner is filled with tree. So, I would not recommend a symmetrical plan. If you want symmetrical around the porch, that would work.

Further, unless those trees are dead, I don't see how you can have "full to partial sun" on each corner.

I'd go with broadleaf evergreens, rhodos, azaleas, kalmias. But, of course, I'm assuming you can't possibly have full sun under those trees.

Sorry the picture is from about a month ago, is from the street, and those trees are starting to fill in as the season advances. They are actually located in the front yard about 100 feet from the house. One of them is diseased so we are thinking about taking it out. I wasn’t considering the trees so that was my reasoning for going with a symmetrical plan. Thank you for your advice.
