With over 200 gardens to discover, it’s worth taking the time to plan in advance what you want to see. If you're looking for inspiration, this page brings together some of the highlights of this year's event.
The London Parks and Gardens Trust is focusing is on three themes for 2018, and you can explore all of these in your garden visits: commemorating the bicentenary of the death of influential landscape designer Humphrey Repton, whose work can be seen in the grounds of the Royal Hospital for Neuro-disability in Putney; the 100th anniversary of the end of WW1, brought into focus at Roe Green Walled Garden, part of a garden village built for aircraft factory workers; and the important role that women have played in gardening and garden design. This last is the easiest to access: many of our spaces are shaped by female gardeners and designers, including the magical Cable Street Community Gardens, managed by Jane Sill for over 30 years.

The sculpted, linear Alexandra Road Park features a series of outdoor rooms and play parks, while the Barbican Station Pop-up Garden is the first community garden on the Underground. Everything at The Skip Garden, Global Generation is built using recycled materials - and the whole community garden is movable!
At the homeless charity Providence Row Rooftop Garden the fruit, veg and herbs grown feed 30 to 50 rough sleepers every day. The Coutts Skyline Garden grows a breath-taking variety of organic produce around a narrow walkway on the roof.
One of the most inventive ways to combat a lack of horticultural space in cities is with a roof garden.
Eversheds Sutherland Vegetable Garden was once a blank corner amongst machinery. Now, the garden nurtures edible and ornamental plants as well as beehives, and offers iconic views across London. Nomura International PLC's vast roof terrace offers panoramic views of the Thames from formal gardens, and an award-winning, volunteer-run kitchen garden.
The vibrant roof garden at Sir John Cass's Foundation Primary School has raised beds full of soft fruit and vegetables surrounded by bee-friendly planting.
Many of our gardens are linked to the story of London's wider regeneration, and others show how local communities come together to create something green and beautiful from derelict and unloved spaces.
The Queen Elizabeth Olympic Park is a shining example of how to restore and repair a neglected and contaminated urban area. 100 hectares of new parklands have been created, including the largest wildflower meadow ever planted in the UK.
Winterton House Organic Garden is an award-winning horticultural oasis and allotment created from a former rubbish dump in East London. At Canary Wharf the Crossrail Place Roof Garden is an exotic space sitting atop the new Crossrail station - part of the transformation of London's Docklands. Lavender Pond and Nature Park was created as part of the regeneration of the Surrey Commercial Docks, and is an impressive example of creative ecology and conservation.
In Hoxton, The Growing Kitchen was transformed from a disused site into a beautiful shared garden with micro-allotments and a communal foraging area. The land at Dalston Eastern Curve Garden had been derelict for 50 years, but is now a vibrant community space.
The Alara Permaculture Forest Garden was created from unused land close to King's Cross, and involved the removal of fifty tons of rubbish to make way for an expansive forest garden, vineyard and orchard.
