Genus guide
Gardenia — 9 species
Gardenias are celebrated evergreen shrubs and small trees in the coffee family (Rubiaceae), prized for their intensely fragrant white flowers and glossy deep-green foliage. Species such as Gardenia jasminoides, White Gardenia, Tahitian Gardenia (G. taitensis), and Savanna Gardenia thrive in bright, indirect light or part sun and demand consistently moist, well-draining acidic soil — never waterlogged and never bone-dry. High humidity is essential indoors. All Gardenia species are toxic to cats and dogs; the compounds genioposide and gardenoside cause vomiting, diarrhea, and hives.
