I posted this picture in the garden visits thread. It was taken during my Burton Agnes visit the other day. Can anyone confirm that Saccharum Ravennhe is correct or not for this amazing plant? Thankyou robert
Google seems to think that Saccharum Ravennae is a grass and not the lovely flowering plant you are holding may I suggest that it's Filipendula rubra?
That could be it Aesculus, common name "Queen of the prairies" On google images it looks the same to me.
