The ′Crown Jewel′ Gardenia was selected from a controlled cross of ′Kleim’s Hardy′ and ′Chuck Hayes′ and developed by Oakmont Nursery in Chatham County, North Carolina. Oakmont was inspired by the late JC Raulston, of the JC Raulston Arboretum at North Carolina State University, and Dr. Michael Dirr of the University of Georgia.
Gardenia ′Crown Jewel′ possesses many of the desirable traits of its parents: double bloom and cold hardiness of ′Chuck Hayes′ and heavy bloom set of ′Kleim’s Hardy′. It also has a dwarf spreading habit, double fragrant blooms and a soft texture but with much more cold hardiness (Hardiness: USDA Zone 6 to 10).
Gardenia ′Crown Jewel′ also has a heavy bloom set, often later than most gardenias. This extremely compact and cold-hardy Gardenia is the essence of timeless beauty.
