Our Gardenia has started blooming for the first time this summer. The plant is grouped with 4 or 5 Coffees of various sizes. The leaves are similar so I just assumed they were all coffee until it began to bloom. I'm not sure of the cultivar name. The flowers look similar to 'fortuniana' but the rest of the plant looks like 'jasminoides'. I'm leaning towards the first one. It may even be some other lesser known hybrid. It's growing in the tropical room and receives filtered sunlight, high humidity, and temperatures no lower than about 25C when all the windows are open.
