I have a chance to get Nikko blue hydrangeas really, really cheap but they are about 3 inches tall. I live in zone 6 and wonder if I could get them and plant them and either keep them inside my garage or put them in my dining room until spring. I would like to purchase 10 and would be saving a fortune to buy them now this cheap and hold onto them until spring. Do you think either of my ideas would be a good idea?

Yes, you can overwinter the hydrangeas in pots indoors. During this time they should only require minimal care--like monthly watering to keep them from drying out completely. Once spring returns, you can plant them outdoors or keep them in containers outdoors to overwinter inside each year.
