Is there any gardenias that climb at all?
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.
