need help with shrub border
I'm looking for some help in planning a shrub border for privacy. I'd like to use a mix of shrubs and hoping I can layer some heights, but not sure I have enough room. Most of the shrubs that are tall enough seem to grow too wide. I live in zone 5. The area faces East/West and is approx. 27 feet. I have a couple pics. I plan on moving the Rose of Sharon's to other locations, as I'm not fond of them other than when they're in bloom. Some shrubs I'm considering for the background are Weigela, Viburnum (summer snowflake or judd??), abelia, summerwine ninebark, fineline buckthorn. Are these good choices? Are they too large? How many to plant? Do I need an evergreen shrub-suggestions? Any advice is most appreciated, thank you!
