Since New Haven is in growing zone 6a this means that plants there can survive temperatures as low as 10 to 15 degrees Fahrenheit. Plants chosen for New Haven's climate should be chosen with this in mind or plants should be moved inside to keep their core temperature in the right range if necessary.
