This is a clump that I've had for quite a while, it's Korean Hornbeam. I think it might be the first one of many that I've had. The pot is Koyo, and sorry it's a bit dirty right now. I got the tree from Don Blackmond. This one is quite slow in its growth habit, some are slower than others. In need of some wiring and a haircut. I usually work the maples first then do the hornbeams later in winter. This one has some issues with all the trees being in the same front to back plane, and some people also would not like the fact that it is 4 trunks, so it's always been sort of a conundrum. I'm sure I have a thread here for the tree somewhere where all this is discussed, if you want to look further.
