All of our Gardenias are bud and bloom now. Walking by the Gardenia beds is so heavenly to the senses! Not only do they look beautiful, but they smell great too. The Crown Jewel Gardenia is a newer variety that exhibits improved cold hardiness. Mature size is two feet tall by five feet wide. Grown in full or partial sun, the Crown Jewel Gardenia is a great addition beside porches, patios, walkways, and under windows.
