Botanical Profile

Growing Gardenias

Native to China, Japan, and Taiwan, this shrub grows 3–6 feet tall and wide. The 2–4 inch flowers are single or double, powerfully sweet-scented, aging to creamy yellow. Bloom time is late spring to summer. It requires acidic soil (pH 5.0–6.0), consistent moisture, high humidity, and bright light (morning sun, afternoon shade).

Hardy in zones 8–11; in cooler zones, a demanding houseplant. Common issues: bud drop (stress), yellow leaves (iron chlorosis in alkaline soil), pests (whiteflies, scale). Use acid fertilizer, mulch, and monitor water. The fragrance is unmatched—a garden treasure worth the effort.
