Does anybody know if any of the following are hardy to zone 5B, I'm looking at some seeds on the LA but not sure if it would be a waste of time and money never mind a waste of seeds. There are crosses involving "Fourth of July in Georgia", "Dr Celia Stump", "Briar Patch" and "Home of the Free"
. I've seen some of these used as pollen plants from northern growers but not as pod parents. I have some evergreens in my garden but I know not all will survive in my zone. Any thoughts?
