What makes British gardeners among the most creative, daring and individual in the world? Rachel de Thame, writing in the new edition of Savills Barometer magazine, believes it’s because "we have no equal when it comes to passion, knowledge and ingenuity."

For centuries British gardeners have travelled the world, collecting a vast range of plants from every corner of the globe. They share their seeds, their cuttings and their expertise with other gardeners. And, says Rachel, they have "taken to social media like proverbial ducks to water, with a vibrant online community sharing cultivation tips."

Meanwhile, the following gardens are guaranteed to appeal to anyone with green fingers.
