One of the most fragrant shrubs in any garden. Gardenias are subtropical and perform well in Perth's warm summers, though they prefer slightly acidic soil and consistent moisture. Full sun to part shade. Well-drained, slightly acidic soil. Mulch heavily. Water regularly. Feed with an acid-forming fertiliser. Treat yellowing with iron chelate. Gold Magic produces double flowers that open white and gradually age to deep golden-cream - the two-toned effect of white new flowers alongside golden mature flowers on the same plant is striking.
