I have no idea, I'm afraid.
Mine hasn't grown much in the 2.5 years I have been here. I am going to prune it this year after flowering, for first time.
Actually, edit: I did remove some lower branches last year to make it into a canopy shape - less bushy .
My neighbour has one that is a 3m tall tree, complete with trunk. Obviously, different varieties exist.
I'm sure you know that it is a ceanothus.
