Other:you could plant conifer,J-maple,zelkova,tea olive,laurel,bamboo,hydrangea...in Zone 7.but good matching the yard need to see the some yard photos.I prefer add some ideas on the photos.You really need to post some pics that show the context and situated and conditions(if have,include drainage irrigation)and the property and the perimeter line (They are not too close up.a panoramic shot is good).
first upload photo to any photo-hosting site.Photobucket and Flickr are examples . While at that photo on the site,
look for a link to "share." Then look for a way of obtaining "html code" (don't select the thumbnail version.)
Copy that code and paste it directly into your message here.
