Any idea what this shrub is ? it was given to us by a neighbour who has no idea what it is. we want to plant it in the ground but have no idea how big it will grow.

 

It vaguely looks like some kind of Privet.(Ligustrum)

 

So, if it get to big it should be ok to cut it back quite hard.
Thanks for the reply.

 

Hang on, I'm just guessing, its certainly not the normal hedging type.

 

It does look like Privet. The habit seems to be ok for hard pruning, perhaps you could take some cuttings now in case things go wrong?

Here's something similar Ligustrum Japonicum Texanum Japanese Privet Hedging Shrubs
