Indoor /Outdoor Gardenia plant….and Hydrangea.
I am a novice gardener. I have a gardenia plant hat was sent to me thru a florist last year for mothers day. I kept it indoors last summer and thru the winter (about 10in high) This spring I transplanted it into a large outdoor container (24" by 18"deep) and it did great outside this summer. We can get some pretty bad winters here and I want to know if it will survive outside, or do i have to bring that big container indoors for winter? I live in PA. I also have same question and situation with a Hydrangea ?

You are right to be concerned about the gardenia survival outdoors during winter. You are in USDA Plant Hardiness Zone 6a. Even the "cold-hardy" varieties of gardenia will be frost sensitive there. So bringing it indoors to a sunny window exposure will be the safest way.
The same goes for the hydrangea, depending on the variety.
