Gardenia
Gardenia jasminoides, G. augusta, G. thunbergia, G. taitensis
The sweet fragrance and creamy, elegant blooms of the gardenia shrub make it a cut-flower favorite for romantic occasions and a lush addition to gardens. Gardenias thrive in bright light, cool temperatures, and moderately humid air- happiest in coastal south and west US and frost-free climates of Australia. Gardenias can be grown as a houseplant, but it is difficult to keep humidity levels high enough for the plant to thrive and they attract pests like mites, mealybugs, and whiteflies.

Growing from Seed
Growing from seed is not recommended. If you do choose to grow from seed, plant seeds in evenly moist seed-starting medium and place out of direct sunlight.
Planting Considerations
Gardenias prefer 65-70°F (18-21°C) during the day and 60-65°F (15-18°C) at night and high humidity levels, around 60%.
Feeding
Feed every 3-4 weeks with an acidic, slow-release fertilizer.
Harvesting
Cut as flowers are opening.
Pruning
Prune directly after flowering. Prune tips after planting to promote bushy growth.
