This is what greets you as you enter the show grounds via the Palladian Bridge. Jonathan Moseley’s floral extravaganza is a foretaste of what’s to come. Rising from the River Derwent is the base of a willow snake, inspired by the Cavendish crest. It is covered in waxy-textured flowers and succulents to evoke the serpent’s scales. As soon as I saw it, I hoped the show would be as spectacular. And it is. I travelled a long way today to visit the show, and I’ve come home smiling-all the way down the M1.
