Gardenias. Our are nowhere near as big as yours! We moved as year and completely relandscaped both the front and back yards. Still, ours are growing like crazy and blooming like yours are! Where do you live and how do you handle them in winter (if it is a concern)? We are in Goochland County in central VA. I am covering mine with burlap in the worst of the winter even though they are the "Frostproof" variety.. Had the same at our old house about the size of yours. One of our favorites!
