We have 3 Fragrant Sumac Lo-Grow that were planted in front of the walk before we moved in. Bush 1, nearest our driveway, had at some point had all the middle cut out, and has always looked weird. I pruned it back off the driveway and walk yesterday, and pulled the mulch and a root that had grown around the truck off. Bush 2, in the middle, looks pretty good, I did the same with it, and noticed it has 2 crowns (do you call them that in shrubs?) a couple inches apart. Bush 3, next to the neighbors driveway, is farther away from the other 2 and is already hanging over their driveway. I haven't touched it yet.
