Gardenias love acidic soil and need to be fertilized (with blue hydrangea food, for example), to keep the soil acidic. G. augusta ‘Golden Magic’ (yellow gardenia) has dark green, glossy foliage and pale yellow, fragrant flowers in summer. ‘Madonna’, with variegated foliage and fragrant, pure white flowers from spring to summer, is excellent for borders and near patios. ‘Radicans’ is low growing, reaching only 300mm and, with its spreading habit, makes an ideal ground cover for warm areas.
