Answer: Most evergreens are not very fast growing, so fast will be somewhat relative. You might look at some of the columnar-formed arborvitaes, hollies, or possibly Leyland Cypress or even a larger cultivar of rhododendron. Your local professionally trained nursery staff and county extension may have different suggestions based on a more detailed understanding of the growing conditions (soil and moisture conditions, wind, sun, etc.) in the site where you want to put these, as well as your design goals. Good luck with your screen!
