I have bought an acer negundo flamingo. The plant label says it will reach 1.5 metres is pruned and 3 unpruned. All the books I've looked at suggest it will be much bigger. Is the label wrong? Or is it likely to be on a different rootstock? I've placed it by the wall to my house and am worried that if it does get as big as the books say that it will ourgrow its space and damage the foundations of the house. Any ideas from anyone?
