Basic info
Gardenia jasminoides is an evergreen shrub native to southern China and Taiwan. It is widely cultivated as an ornamental plant for its shiny dark green foliage and large, fragrant white flowers that bloom from May to August. The plant grows moderately fast and typically reaches heights between 60 and 150 cm. Gardenias thrive in partial shade and prefer loose, well-drained, slightly acidic soil.
Care requirements are moderate, needing regular watering and fertilization during the growing season. It is frost-sensitive and requires protection during cold months, whether grown indoors or outdoors. Pruning after flowering helps maintain its shape and encourages new growth.
Gardenias are popular both in gardens and as houseplants, especially among those who appreciate fragrant blooms. They attract bees and other pollinators, supporting local ecosystems.

Care
Gardenias require regular but moderate watering to keep the soil slightly moist without waterlogging. They prefer partial shade with no direct harsh sunlight. Fertilize monthly during spring and summer with fertilizer suitable for acid-loving plants. Prune after flowering to maintain a compact shape. Protect from frost in winter by keeping indoors or covering if planted outside.
Propagation
Propagation is mainly done by semi-hardwood cuttings taken in spring or early summer. Using rooting hormone and maintaining a warm, humid environment improves success. Division is less common, and seed propagation is slow and unreliable.
Diseases & pests
Gardenias can be susceptible to aphids, spider mites, and fungal diseases like powdery mildew. Good air circulation and avoiding overwatering help prevent problems. Regular monitoring and treatment with appropriate pesticides may be necessary.
