Gardenia is a genus in the Rubiaceae. It is loved for glossy evergreen leaves and creamy white, waxy, rose-like flowers with a rich perfume that’s strongest in the evening and early morning. Gardenias work beautifully as shrubs, hedges, specimen plants, and container plants. 

This plant can also be grown as potted indoor plants in cooler climates where winter temperatures dip too low for outdoor growth. 

Most gardenias bloom from late spring into early summer, and some varieties rebloom sporadically throughout summer. 

Gardenias are hardy in USDA zones 7-11 and perform best in warm, humid conditions with acidic, well-draining soils.
