Guy Cooper and Gordon Taylor, drive an 1960s Alvis sports car around the gardens of Britain - the traditional, the eccentric and the contemporary - and talking in their informed, cantankerous and humorous way about the unusual and interesting elements of design they have found.

In their second series, the Curious Gardeners explore how traditional and contemporary garden design relates to the planning and planting of contemporary gardens. They look at design components - water, materials, form, sculpture, planting and time - and design a city garden from scratch.
