Gardenia is a classic small to medium size broad-leaved evergreen shrub. The 2 inch to 3 inch diameter fragrant white flowers show well against the dark glosy green foliage in late spring to early summer. These southern shrubs work best where they receive morning sun to day long part shade. Plants grow best in similar conditions as Rhododendrons, Azaleas, and Camellias.
