I have two books that explain each varieties characteristics. Some Japanese maples need shade, while others will tolerate sun. If you see a maple you like you need to write down its' name and check if it will tolerate sun. Growers are always developing interesting weeping evergreens. These plants are deer food.
Many junipers are rather deer resistant.
Many weepers get to be 10 feet or more tall. You don't want to prune a weeping plant to keep it small. You will destroy its' lovely shape. This should get you started. If you see a specific plant you like you can e-mail me about it.
