The varieties that are considered more hardy are Chuck Hayes, Klein's Hardy, and Daisy. Are there other August Beauties in your area? Here in Vienna even the hardier gardenias are an impossible dream....I've never even thought beyond the issue of winter cold so my first instinct would be to cosy it up to a brick wall.

sorry about the typo--it's Kleim's Hardy

Here in Chesterfield there are gardenias that do very well but I'm sorry to say I don't have a clue as to their variety. Most have been around for many years and nobody remembers when they were planted or what they are. I would suggest that you ask around in your neighborhood of anybody that has them growing to see what variety they have (if they know!) Your cooperative extension agent might be of some help, too.
