The trunk is extremely nice for a nandina. Plant Dr. and Chris have geat ideas on where to go with it--however Dr's pot is a bit ambitious (and dangerous horticulturally) within the next five years.
The issue you're going to be fighting with this species, however, is ramification and branching. Nandina does both reluctantly Sends up single shoots very easily though. Turnk makes this worth the battle though...maybe, until you get frustrated
