The 2.5ha of gardens tell the story of Edward Augustus Bowles, one of Britain's most famous self-taught gardeners, artists and expert botanists.
The gardens, based in Bulls Cross, Enfield, are free to enter. They have a tea room and museum, plus restored glasshouses and kitchen garden. They are also home to a carp lake, a Victorian conservatory and a number of historical artefacts collected and treasured by E A Bowles, including pieces from the original St Paul's Cathedral and the Enfield Market Cross.
