Pests in Gardens and Landscapes

Gardenia (Cape jasmine)—Gardenia augusta
Family Rubiaceae (Madder family)

Plant identification

Gardenias are known for waxy white fragrant blooms upon large dark green leaves. Plants are grown as evergreen shrubs, groundcovers or as a formal standard. They can also be espaliered. They can grow up to 6 feet tall.

Optimum conditions for growth

Gardenias are best grown in rich organic soils with acidic pH. They require well-drained soil. Avoid crowding with other plants and use surface cultivation. Plants do best in partial shade in hot inland valleys. Avoid high salt conditions. Mulches may help conserve water and decrease soil temperature fluctuations.
