This spring I bought a small hydrangea (4 inch pot) that was labeled as a new
variety designed to stay small. Or something like that. It said it was only
hardy to zone 7 (I'm zone 5b). It's been sitting in a pot on the patio all
summer. The blooms are now starting to fade so I'm wondering what to do with
it. Will it survive being wintered indoors, or do all hydrangeas need a period
of dormancy? This is not a florist's hydrangea, unless the labeling was
deceptive.
