Yes. But . . . moving it (therefore maximum root disturbance in summer) will be potentially damaging. Masses of water prior to the move, then cut it back, and move it. Masses of water again and you may get flower later this year.

I agree and take as much soil around the roots as you can to minimise root damage. I'd certainly prune it down to about 1-2ft tall. Keep it in a big pot/bucket in the shade to prevent the root ball getting too hot too.

Thank you both very much, will try the move today.
