after a few trial and error with placement I opted for an interesting design that I am happy with...

from right to left I placed a grouping of Azaleas which i hope to grow into a nice hedge under the bay window mixing purple, pink and white shrubs. Next I placed a Diablo ninebark tree form shrub to help fill the gap between the bay window and the next window and in front of that another spreading Azalea shrub that for lower coverage with about 12" or a little more of height. Next I am experimenting with a Yaku Princess Rhododendron which I may move a little but I opted for this one since it is known to grown more compact than typical Rhododendrons. Under the two high windows running the length of the foundation I opted for a row of five boxwoods that should form a nice hedge that will reach about 4' - 5'. I opted for lower coverage since we plan on moving the high window over more and replacing with a normal double hung more centered in the room which will move it over and I didn't want to plant anything I would have to move that may block the future window. I then opted for 3 crimson dwarf and 3 golden dwarf barberry. The only problem I am having is what to place at the end of the landscape. I was thinking of a nice tree like a crape myrtle or something else but I am open to suggestions.
