London's gardeners are twice blessed: not only do they live in one of the world's most vibrant capitals, it is also one of the most verdant. Gardens of every imaginable style, shape and size abound on rooftops, within palaces, surrounding churches, behind walls - on every piece of dry land - even if it is floating on or lapped by the river Thames.

In Great Gardens of London, Victoria Summerley and Hugo Rittson Thomas collaborate to unearth the most fascinating stories of plants and people inside London's most exciting gardens. Some of the gardens are strictly private, while others are regularly open to visitors, but all can now be savoured and enjoyed along with those who know them best.

Great Gardens of London is a captivating photographic portrait of the greatest gardens of the capital which are primarily closed to the public or rarely open their gates. It will feature gardens designed by some of the leading contemporary garden designers from across the world. Accompanying the photographs will be essays on the design and planting that explain the designers' inspiration and passion.
