I haven't really noticed any aroma from my Miracle fruit, at least not from a distance.
As for Jujube, I do not find it foul smelling at all, my plant smells a bit like citrus. some cultivar imported from Taiwan, but suspect it a Z. mauritiana.
My favorite though has to be citrus, I just love the smell, growing up in central Florida, I guess its tied to childhood memories.
I agree the cannonball tree flowers, smelled nice, plus they are pretty also.
