Answer: Very few trees will grow well in deep shade -- if you think about it, the center of a forest is usually fairly bare except for the trunks of the tall trees. In dappled light you could try a redbud (Cercis canadensis) or the native dogwood (Cornus florida) or possibly a blackhaw viburnum (Viburnum prunifolium) or maybe the semi-evergreen to evergreen Viburnum rhytidophyllum. These trees are understory plants in the forest but usually grow along the edges or in bright dappled areas where there is a bit of direct sun. They do not usually require any spraying. In my experience you will need to protect any young trees from deer by encircling them with a fence or possibly applying the commercially formulated deer repellents per the label instructions. Your local professional nursery staff and/or county extension may have additional suggestions based on a more detailed understanding of the planting site and your design goals.
