The genus Gardenia was named after Dr. Alexander Garden, an 18th-century botanist. The species name “jasminoides” means “jasmine-like,” referring to its fragrant flowers.
Cape Jasmine is native to parts of South-East Asia. It has been cultivated for centuries in China and Japan for its beauty and medicinal properties.

The plant features:
- Thick, lustrous, lance-shaped dark green leaves
- Fragrant white flowers, about 3 inches (8 cm) across

The flowers bloom throughout the year in warm climates. In cooler regions, they appear in late spring to early summer.
Gardenia jasminoides prefers partial shade and well-draining, acidic soil. It thrives in temperatures above 60°F (15°C).
Cultivation and Care
Gardenia jasminoides thrives in specific conditions and requires attentive care. Proper growing conditions and regular maintenance are key to keeping these fragrant evergreen shrubs healthy and blooming.
Optimal Growing Conditions
Gardenias prefer warm, humid climates similar to their native Southern China and Japan. They grow best in USDA zones 8-11. These plants need:
- Partial shade to full sun
- Well-drained, acidic soil (pH 5.0-6.5)
- Consistent moisture
- High humidity
Plant gardenias in spring or fall. Choose a spot with morning sun and afternoon shade. Improve drainage by adding organic matter to the soil. Space plants 3-6 feet apart, as they can grow 4-8 feet tall and wide.
In colder regions, grow gardenias in containers to move indoors for winter.
Maintenance and Pruning
Regular care keeps gardenias healthy and blooming. Water deeply once a week, more in hot weather. Apply a 2-4 inch layer of mulch to retain moisture and suppress weeds.
Fertilize monthly during growing season with an acidic fertilizer. Prune after flowering to maintain shape and size. Remove dead or crossing branches.
Watch for pests like aphids and mealybugs. Treat promptly with insecticidal soap or neem oil. Yellowing leaves may indicate nutrient deficiency or poor drainage.
Provide extra humidity indoors by misting leaves or using a pebble tray. Gardenias can be fussy, but proper care rewards you with beautiful, fragrant blooms.
