Thanks to all for your very helpful advice. The hydrangea is not a named one, it was half price on the clearance bench at Homebase, couldn't resist buying it! For now I plan to leave it in a pot on the patio. When / if it gets too big I will plant it in the ground.
I will let you know if it remains white next summer. Managed to get 8 cuttings off it, usually get a good success rate with Hydrangeas hope these take!
