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.

Thanks. I'm new to gardening/landscaping and this put me on the right
track. Here's one of the many links I found.
