I have seen a bloom on one once, and it was so intruiging, but lordy, it was odorous.
Helen, When I was growing up, My neighbor had a "tree of heaven" and my mom and I would sneak over and pour boiling water with a pound of salt around the tree to kill it. It took many pounds to eventually kill it but it was such a disgusting tree we had to banish it. Of course, we would only do this when my neighbor traveled........he was gone weeks at a time investigating airline crashes.
Yep, you guessed it, he figured out what killed his precious tree. I can still see the look on my moms face when she was confronted by him ..........with him licking his fingers and saying it tasted like salt to him.
