Gardenias Outside

Asked October 4, 2018, 1:01 PM EDT

Hi, I have a large potted gardenia on my porch. I have been told I can plant it outside and it will survive the winter. Is this true? How can I tell the difference in a hardy and a tender gardenia? Is it too late to plant this year in order to establish for overwinter survival? Thanks,

Most gardenias are not hardy in Maryland. 'Kleim's Hardy' is one that has been specifically bred to survive in Zone 7. If that's the variety you have, you're in luck. We are not familiar with any way to distinguish a hardy from a non-hardy gardenia.
