Blueberry zone hardiness question
I just bought a Premier Blueberry bush at a local Lowes. I'm in zone 5/6. The tag said it was hardy to zone 3. But while doing research on the net I see that it is only hardy to zone 7. Naturally I'm confused. I know very little about blueberries, and now am afraid I made a mistake. Can anyone help me with this issue? I haven't planted it yet, and want to return it if it is not hardy here.
