I have a common red hibiscus to this area, I'm not exactly sure what cultivator it is because when I first purchased it I was new to the whole realm of hibiscus, so I didn't keep any labeling. I've had it for about 4 years and it always blooms profusely throughout the summer months. During the winter many of the leaves fall off, but once it warms up it comes right back. It's done wonderfully. Though maybe its just me, but it seems to be a slow grower, maybe now that I have it in a larger pot it may make a bigger jump.
