I've got a handful of them growing on the edge of my property. The "sweet little lady" next door, knowing full well where the property lines were, planted them 10 feet into MY property. When it came time to have some trees removed I had a discussion with my neighbors and found out that the property lines weren't where I thought they were. She admitted planting them there (years before I bought the property) and told me that now that I'd had trees removed, she'd clean up the loropetalum she'd planted (and the ivy that was creeping into my property*). I gave her 9 months before I went in and cut them back to about 24". Basically bare stumps, even at that height. They're hideous right now throwing whips every which way, but no worse looking than they were. I'm planning on digging them up in the spring and planting Satsukis. They've got 3-4" trunks.
*Who plants ivy at the edge of their property?!?
