Joseph's Take
Kleims Hardy has been my favorite Gardenia for years. I have planted many of these for the dark green evergreen foliage and especially the amazing fragrance of the flowers. I especially use any Gardenia against a white fence or house. Kleims is a relatively strong gardenia if you live in a cooler climate. Soil desires are acidic, water needs are minor. Best planting location is near a protective structure with dappled sun.
