Answer: Based on the information in your question I am not exactly certain how much space you have available for your new/replacement plants. If the area is partly shaded by the surrounding trees you may want to try something that will tolerate a bit of shade such as additional hollies or perhaps a deciduous understory tree such as a dogwood. Or you might consider using a large shrub, maybe a viburnum or even a large rhododendron such as R. catawbiense. Keep in mind you need to allow space for them to grow and mature without too much crowding, and if the other trees are large there may be some root competition to take into account as well. I hope this helps you get started in thinking about what to plant. Your local professional nursery staff and/or county extension may have additional (or different) suggestions based on a more detailed understanding of the planting site and your design goals.
