They only sucker if not grown on their own roots. If they are grafted...then, yes they sucker. I researched them before planting one in my yard. I found one on its own roots and has not tossed one sucker. But...finding one on its own roots is the key. Called many nurseries before finding one that wasn't grafted.We get that plant around here, its also called Harry Lauder's Walking Stick and we also get a red leafed variety called Red Majestic. Very interesting growing shrub but the leaves can be on the large size and very coarse, I have seen small leaves on summer growth though. This would probably be better looking in the winter without leaves. I've seen considerable leaf scorch in the hot sun, but that may not be a problem for your area. Watch out because they like to sucker.
Good luck!
They are very slow growers...the red majestic isn't as cold hardy either. Quirky tree/shrub. The poster would thicken it better in ground with it such a slow grower. That in and of itself...along with its not known for very good leaf reduction. Mine will remain in the lawn where I can enjoy it.
