We saw it at the show. Without the explanation on GW I wouldn't have understood what it was all about. Still had plenty of interesting elements to the garden for those not 'In the know'.
As an aside, that was one of the lucky gardens as it seemed to have survived the rain of Thursday and the gales of Saturday. Some had been severely damaged. We were talking to the designer of one who said the tall hedge on hers had been dragged back up almost to upright by attaching guy ropes to the back!
It must have been soul destroying after all the work put in.
