Answer: Your plant is Gardenia jasminoides and is hardy to about 20F. It's unusual for temperatures to get below that in your maritime climate, but it's possible, so plant your gardenia outdoors in a somewhat protected area such as close to the house, preferrably under an eave. It should also be quite happy under some trees and next to other shrubs which will help protect it from ice and snow. Best wishes with your new gardenia!
