Beautiful dwarf flowering broadleaf evergreen provides exquisite fragrance in summer and is the jewel in the crown of the winter landscape.
Crown Jewel®Gardenia PP19896 is a low-growing, spreading to prostrate gardenia with intensely fragrant, white, medium-sized double flowers beginning in early summer and repeating until frost. The heavy May flush of blooms is followed by repeat blooming throughout the summer, until fall brings another heavy flush of blooms. Light pruning after the first bloom-period will stimulate even more blossoms. Crown Jewel® Gardenia blooms on both old and new wood, so late frosts will not harm the crop of fragrant white flowers
Highly perfumed Crown Jewel(R) Gardenia is an easy care broadleaf evergreen hybrid in a versatile dwarf size, and requires little if any pruning to stay in shape. This garden jewel grows about 6 inches per year with the potential to reach 2 or 2 ½ feet in height and a spread of 4 to 6 feet wide, ideal for garden beds. The plant is hardy to zone 6 and bright green evergreen foliage is medium to small-sized for the species, with a soft texture overall.
Crown Jewel® Gardenia is the very best selection from a controlled cross between dwarf ‘Kleim’s Hardy’ (dwarf habit, heavy bloom set) and ‘Chuck Hayes’ (cold-hardiness, twice-blooming, double flowers) by Philip Dark of Oakmont Nursery in Chathem County, North Carolina. Dark is a member of the consortium of growers, breeders, retailers and marketers that make up Garden Debut®, and he reports that cold testing is ongoing in Zone 5.
CrownJewel® Gardenia prefers well drained, moist soil and full sun to partial shade (a bit of afternoon shade is great) and good air circulation. A cooler, woodsy environment protects from the harsh reflective heat of concrete or asphalt. Shelter from cold winter winds helps to prevent tip dieback at the colder edge of the plants’ range. Organic compost is excellent or light applications of commercial azalea fertilizer or diluted acid-forming fertilizers are good, although too much can burn tender roots.
Among its many landscape uses, Crown Jewel® Gardenia is perfect as a specimen adding color, fragrance, form and texture, a low accent plant in the garden; for winter interest; or as part of mass plantings. It is an excellent evergreen plant for containers where the fragrance can be enjoyed on decks and patios. While cold-climate gardeners must over-winter their gardenias indoors (can be grown as a houseplant or a patio plant moved indoors in winter), in U.S.D.A. Climate Zones 6 and warmer, gardenias are grown outdoors, permeating the garden with fragrance. (Testing in Zone 5 is ongoing.)
This genus is native to the tropical and subtropical regions of Africa, southern Asia, Australasia and Oceana. Gardenias are easily grown in the southeastern U.S. because they demand high humidity and rich, acidic soils to thrive.
