This lovely plant was once a single stick - which we planted on the very left. The 'tree' grew to about 12 ft. high. Then we took a cutting and planted it next to this shrub/tree, and that one grew to over 15 ft. (and just as wide).
It's gigantic now, but requires pretty much no maintenance - no diseases, no bugs, little to no pruning (maybe a little bit on the bottom, ther). And it has lots of little white flowers that the butterflies love!
