Gardenia
African Gardenia
Gardenia thunbergia
A wilder, more generous gardenia — single luminous blooms with a creamy, butter-rich perfume that carries on the evening air.
Scent Profile

A lush, buttery cream opening — coconut-skin warmth and fresh white petal.
Heart note
A deep tuberose-gardenia floral, rich and rounded with a faint green stem edge.
Base note
A soft, powdery musk with a whisper of sandalwood as it dries down.

Care notes
Tending this plant
Soil
Well-drained, acidic, and rich in organic matter. Blend planting mix with peat or coco coir and plenty of pumice — gardenias demand drainage yet hate drying out.
Feeding
Feed with an acid-formula fertilizer (for azaleas/camellias) every 4–6 weeks spring through summer. Watch for yellow leaves — a sign of iron chlorosis in alkaline soil.
Pruning
Prune only to shape after flowering. Remove leggy or crossing stems and thin the interior for air circulation to prevent bud drop and fungal issues.
Winter care
Protect from hard frost — it tolerates brief 30°F dips but loses buds and tips below that. Site near a warm wall or under tree canopy in cooler pockets.
Container growing
Does beautifully in a container where soil can be kept acidic easily. A 16–20 inch pot with rich, fast-draining mix and a humidity tray makes a spectacular patio specimen.
Where it grows
A California story
A South African cousin of the temperate gardenia, better suited to California's dry summers than its Asian relatives. Large single ivory blooms open at dusk and hold their fragrance through the night.
