Hi Barbalee -- I'm not sure how helpful this will be, but I think it sort of depends on 'what' zone 5 we're talking about; according to the USDA, I am now supposedly in zone 5, but pansies don't overwinter for me (however, Johnny Jump-Ups self-sow and return in the spring quite enthusiastically!) That said, I believe I could overwinter pansies if I planted them right next to the foundation of my house.
