KayBelize,
No. No climbing gardenias.
BUT, next best thing is Grand Duke of Tuscany jasmine.
Smells soooo good and climbs, don't pinch it off at all.
Dark green leaves, treat it just like a gardenia.
You might have to cut it in the fall and bring it in, but it is well worth the effort.
You could plant it in a pot and try to get it to climb on something.
There are also other fragrant jasmines that you can keep outside and stay evergreen.
I have Confederate jasmine "Madison".
Evergreen, blooms extremely fragrant May and June, some blooms in July. Climbs aggresively, I cut mine back when it grows where I don't want it to. Love it.
