I'm not so sure about that. Road salt has caused a sectionof my
flower garden to be very difficult to grow "anything" in (may have

While I realize you are wanting this area for edibles, rugosas tolerate
road salt extremely well (they like to grow near salt-water too). Some
varieties do produce substantial hips for rosehip tea.
