The RHS Chelsea Flower Show will be flying the flag for a greener Britain in 2017.

As the finest horticulturalists from all over the world exhibit their immaculately-designed gardens, the Royal Horticultural Society will showcase its vision for how gardeners can help turn grey Britain green.

The benefits of nurturing plants and gardens in even the smallest areas will be on show. If you’re feeling inspired and are thinking of attending this year's event, here’s everything you need to know about the RHS Chelsea Flower Show 2017.

What will be on show?

London’s Covent Garden, the Yorkshire coastline and the Chengdu Silk Road have all inspired designers in this year’s show.

The centrepiece show gardens will include one aiming to turn grey Britain green, another inspired by the quarries of Malta and one featuring pines, larches and birches to reflect the boreal forests and freshwater lakes of Canada.

Visitors will also be able to see thought-provoking and unconventional contemporary gardens, with nine Artisan garden designs taking visitors “from Japan to the Mediterranean and back again to the British coastline”, the show’s organisers the Royal Horticultural Society said.

More than 100 colourful displays of every shape size and colour will also be on show in the Discovery Zone science and research hub.

All the marquees, gardens and floral exhibits can be viewed from ground level, but none of the gardens are designed for public access - although some of the marquees and floral exhibits can be walked through.

When is it?
