This past spring I bought a Gardenia "Frost Proof" which is listed as hardy to zone 6 and planted it out against a south-facing wall. It's done very well and I will give it a little protection soon. We haven't had any freezes here yet and none in sight for the next 10 days so far. I have also just heard of one called "Diamond's Fragrant Delight" which is also listed as hardy in zone 6. Has anyone grown either of these varieties in zone 6? I would like to hear of any successes, or failures.
