When one thinks about hedges, it’s really not about a Yew or Leyland Cypress any more, Arborvitaes are what comes to mind. Green Giant and Emerald Green are two of the most popular choices.
These guys are workhorses when it comes to growth. Some can grow 3-5 feet a year!!!! And usually top out at about 50 feet high. (there are some cultivars that are much smaller too) So, if you need a green dense living fence, you might want to consider.
