My beautifully landscaped backyard was destroyed during flooding from Superstorm Sandy. Our arborvitaes are beyond dead, as are several of our other shrubs. We're in Long Island. I am trying to find plants and shrubs that if we are flooded again will withstand salt water, but everything I'm finding is either some form of a noxious weed, can't grow up north, or is poisonous. I'd like something that flowers or that just isn't green all year round. Any suggestions?
