I have one that I trim into a semi topiary, I keep it in bounds, I have another that I planted in a bad spot and let it go... How big will this get eventually? I am thinking I need to relocate it before it turns into a tree.
I groomed mine to a tree and it's 15ft tall. :o)
It does grow as a tree 10-15ft tall. if you are letting it grow as a tree do a lot of selective pruning when it is young and thin it out. If not it tends to grow very thick with lots of cross branching. Also lots of weak branches that will split off.
