Joseph's Take
Much like Heaven Scent Gardenia, Double Mint is slow growing and tightly branched. As with most gardenias, I prefer to plant them with some protection from cold winters by planting near a structure. In zones 8 and 9, cold winters are not an issue. I love the sweet smell of Gardenias so much, I plant them any chance I get.
