doesnt buxus normally have a light tan trunk? thats what throws me off with it, and as bodhi stated buxus have very fibrous root systems.
you will be able to tell soon when it buds out though!
was the trunk buried? might explain why the bark is so dark. how big is the trunk? buxus are slow growers but can get big reasonably quick with sacrificial branching, not that this one has had that done but it could of had low branching at one stage that died off or something to pump its size up
