I planted several here. The first, fifth and ninth are dwarf/shrub Purple Magics. I don't remember the names of the others, but the rest are all full size/tree cultivars

This one we got from the Arbor Day foundation. It was

We never cut ours back to stubs like some people do, we just prune them up some to keep them relatively clean
