Yes I think so to some extent. I have seen typical dimensions after 20 years quoted as 20ft high x 9ft spread, but with an ultimate height of 60ft.( :o)
I have one at the bottom of my garden in anticipation of my rear neighbour eventually chopping down his elderberry tree. Mine has been in now for about two years and is around 7ft high and 5ft spread.
I intend to 'stop' mine before it gets anywhere near the maximum height though. 20ft high would be just about right for my garden.
