The most common plant for this purpose in zone 5 is arborvitae. (Thuja sp)
If the soil is right for them, some people also plant hedges of tightly
growing trees, such as blue spruce, which usually keep branches down to the
ground - they can be sheared to keep them low and thickly growing. I think
it might also be possible to plant hedges of juniper virginiana, a native
tree juniper of the east and midwest. These can also be sheared to be lower
than their normal height of 20 feet plus.

What would be a good fast-growing tree or shrub to use for privacy
screening. An evergreen for year-round screening would be
preferable.
Thanks,

What are you doing that you need privacy?
