Right now all we have growing along that fence are shade perennials that can
be easily moved. We do have a Holly tree not far away in full/mostly shade,
and while not tall nor narrow, it is very healthy. Not very familiar with
Hollies, but I will look into them to see if I can find one that meets our
specifications. We like our neighbors but their house is very close to our
fence and on a hill overlooking that area of our yard. We are just looking
for something to grow a few feet taller than the six foot fence for added
privacy. Thanks very much for the suggestion.
