Fukurinkoba Variegated Gardenia. I found this cultivar in Japan, and it is one of the few variegated forms to which the Japanese had actually given a cultivar name. "Fukurin" in Japanese has to do with marginal variegation. The leaf is the size of 'Mystery' but is a pewter-green color with cream-white margins, and it is by far the most cold hardy of any variegated Gardenia that I have ever seen. We leave our plants outside in full sun exposure all winter with no damage. The flowers are single and fragrant.Professor Fred Thode at Clemson always admonished his students that we should site Gardenias in the landscape so that they don't get early morning sun. This is because when they are heavily frozen on a cold winter morning, if sun immediately strikes them, it appears that they are thawed so rapidly, that it causes a rupturing of the cells of the leaf. Whether or not this is what actually happens, it is very obvious that there is far more cold damage on gardenias here when they are planted on an eastern exposure. When planted on the north or westerly side of a structure, even though it is colder, there is far less cold damage, because the plant's tissue has already thawed by the time the sun strikes them. Thus, if one is trying to grow Gardenias out of their "range," one should take this into consideration. As with all Gardenias, one needs to keep eyes open for the ubiquitous white flies which consider Gardenias as their filet mignon. All gardenias are susceptible to white flies, which in turn secret a sticky honey dew and then sooty mold which grows on this, soon follows. So to prevent the sooty mold, the best cure that we have found is using "worm castings." Sounds too good to be true. But this material which passes through the earthworm prevents white flies and also fertilizes your plant and it is completely natural. WOW! Just amazing.
