Gardenia jasminoides, known as gandhraj, is a prized evergreen shrub grown for its intensely fragrant, creamy-white, rose-like double flowers set against glossy, dark-green leaves. Blooming mainly in the warm months, its rich perfume makes it a favourite for fragrant gardens, pots and cut flowers. Gardenia is more demanding than many shrubs, needing acidic, well-drained soil, steady moisture and good light to flourish. It rewards attentive care with a long succession of velvety blooms. Suited to gardens, shaded patios and large containers, gandhraj is a classic choice wherever fragrance is treasured. Consistent conditions are the key to its glossy foliage and abundant flowers.

Growing tips
In India, gardenia needs acidic soil, steady moisture and bright but not scorching light; in hot plains give morning sun with afternoon shade. Use an acidic fertiliser and iron to prevent leaf yellowing.
