I am pruning my hazel clump, and I am certain it is Corylus avellana,

doesn't grow more than 6m. It was bought as ordinary hedging plants
a long time back, but there are 20 year old stems that reach that
high. Do other people have such large hazels, or is this unusual?

I don't know how many times I've told people that plants *can't* read books!

FWIW, both "Hilliers Manual of Trees and Shrubs" and the "RHS Dictionary
of Gardening" state that Corylus avellana is usually a shrub to 20ft/6m
or, more rarely, a tree to 35ft/10m in height.
