Our database shows optimal zones 6 and warmer for Floribunda Rose (Rosa 'Cinco de Mayo') but maybe with heavy mulching it would be okay in your zone. I noticed a couple of ATP members who are in zones 5a & 5b have photos in the database of this beautiful rose so maybe they can offer advice. @chelle @skiekitty @DsSister
