Burlington Stone from Cumbria has once again made its contribution to winning gardens at Chelsea Flower show - one of which was no less than Best in Show. Broughton Moor riven slate was used by Tom Stuart Smith in his Best in Show creation for the Laurent-Perrier Harpers & Queen display. And Burlington\'s Elterwater Green was used in the Merrill Lynch garden designed by Xa Tellemarche and Jon Kellett that won the Silver Gilt Flora medal.
