Gardenia jasminoides 'Crown Jewel' (Cape Jasmine)

Cape Jasmine 'Crown Jewel', Crown Jewel Cape Jasmine, Cape Jessamine 'Crown Jewel'


Hardier than most Gardenia augusta hybrids, Gardenia jasminoides 'Crown Jewel' (Cape Jasmine) is a small evergreen shrub with thick, lustrous, lance-shaped, dark green leaves and intensely fragrant, double white flowers, 3 in. across (8 cm). A cross between 'Kleim’s Hardy' and 'Chuck Hayes' gardenias, this Gardenia blooms twice a year, on old and new wood. Noted for its ability to survive cold winters and flower prolifically. Perfect for small gardens and containers.

  • This evergreen shrub enjoys a compact, spreading habit and grows up to 2-3 ft. tall (60-90 cm) and 3-4 ft. wide (90-120 cm).
  • A full sun to light shade lover, this Gardenia is best grown in consistently moist, acidic, organically rich, well-drained soils. Although it prefers full sun, some shade is appreciated during the warmer months of the year or its leaves may scorch and its buds may fall off if they get too much sunlight. In hot climates, Gardenias grow best with morning sun and afternoon shade. In cooler areas, they can tolerate full sun, especially if their roots are covered with organic mulch.
  • Perfect as a specimen plant or in containers. Great cut flowers.
  • May be affected by powdery mildew, leaf spots, dieback, anthracnose, sooty mold, whiteflies, mealybugs, scales, aphids and spider mites.
  • Cut off the faded Gardenia flowers, just below the leaf node, to encourage continuous blooming.
  • Prune/shape your Gardenia plant when it is dormant, to promote branching and compact growth
  • Propagate by seed, greenwood or semi-hardwood cuttings
  • Native to southern China and Japan
