Gardenia jasminoides Celestial Star (Cape Jasmine)
Cape Jasmine Celestial Star, Cape Jessamine Celestial Star, Gardenia augusta 'Celestial Star'
Noted for its cold hardiness, Gardenia jasminoides Celestial Star (Cape Jasmine) is a medium-sized evergreen shrub with thick, lustrous, lance-shaped, dark green leaves and highly fragrant, double, white flowers. Blooming in spring, this handsome rounded shrub enjoys a profuse rebloom in fall. Perfect as a low hedge, specimen, or a foundation accent.
- This evergreen shrub has a bushy habit and grows up to 3-4 ft. tall and 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 and useful as hedges 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. Deer resistant.
- 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.
- Toxic to dogs, toxic to cats, toxic to horses.
- Native to southern China and Japan
