Yes, I believe this tree is usually pruned back to keep it a manageable size, but perhaps someone else could just confirm!

Celyn Vale Nursery specialised in Eucalyptus. Unfortunately, after a very sad accident, it closed some time ago.
However, some of what I believe are its web pages still seem to be operating, including the one on coppicing.
E. niphophila is listed as having poor coppicing ability - although it may regrow from its lignotuber if cut back.
See http://www.blueram.net/eucalyptus/indepthguide/coppicing.asp for details.

What was the sad accident? I went there about two years ago and it seemed abandoned?

Ooops, sorry, I stand corrected!

Fractal - I've just sent you a PM.

Thanks Longleaf, had a look on the website, its very informative, may cut it into a "hedge" instead!
