‘Crown Jewel’ typically grows to only 2' - 3' tall but spreads to 4' wide. It is particularly noted for its dwarf spreading to prostrate form, heavy bloom of fragrant, double white summer flowers (to 3" diameter) and excellent winter hardiness. Flowers appear in early to mid-June. Light pruning after flowers fade may encourage some additional bloom. Blooms appear on both old and new wood. Elliptic evergreen leaves (to 2" long). 'Crown Jewel' is the result of a cross between Gardenia jasminoides 'Chuck Hayes' (female parent) and Gardenia jasminoides 'Kleim's Hardy' (male parent) which originated in a controlled breeding program commenced at Oakmont Nursery in Siler City, North Carolina in 1998. 'Crown Jewel' was selected from the breeding program in 2000 based in large part on its double bloom and dwarf-spreading habit. U. S. Plant Patent PP19,896 was issued on April 7, 2009.
