Full white flowers with a texture like the finest suede, glossy dark foliage with distinctive veins, legendary scent - Gardenias have it all. These trees bloom most prolifically from March through June, with flowers that emit an opulent fragrance, one that has been used for centuries in the making of perfumes. Gardenia bonsai can manage light frosts. Thrives outdoors in wind free sites above 20 degrees, see Bonsai Care. Agricultural Regulations prohibit us from shipping Gardenias to Arizona.
