This is one of those questions that is difficult to answer since there is little clue about the amount of daylight the areas is actually getting. Is “some sun” one hour or 6 hours. There is a wide range of possible amounts between “some sun” and all day sun. The best I can suggest is a Weeping Japanese Maple. They are $150. With 7 hours of sun, weeping cherries and snowfountain crabapples would be possible to grow in that location as well. They run about $100-$150.
