GoldDoubloon™ Gardenia. When I first saw this Gardenia in Japan in late 2010, I was in awe of its striking gold foliage. Without a doubt, this is the most incredible variegated Gardenia of all time, as one can clearly see from the photos. On top of this, it has double fragrant flowers which measure between 4.5-5" across. All of the variegated Gardenias that I have seen up to this point have single flowers, except for Gardenia 'Double Variegated', which seldom flowers. The leaves are also the largest of any Gardenia that I have seen. Overall, this plant is a "traffic stopper!" For best foliage color, plant it where it gets at least a half day of full sun. When it first leafs out in the spring, the foliage is more chartreuse, but as the season progresses, the variegation becomes brilliant golden-yellow as one can see in the photos. We don't know why, but for some reason we don't have near the problem with white flies that we have on green-leaf varieties.
