I originally was going to put in a line of Arborvitae pyramidalis (emerald green) along the east side of our church, but some more research showed that the salt from the parking lot could make this a poor choice. Can anyone point me to a shrub similar is shape (upright, 3-4 ft diameter, good for a hedge perhaps eventually) that is more salt tolerant? We're in MI, zone 6.

Thank you!
