More than 200 projects have signed up to the Fringe, against 100 in 2012 and this time events will take place in Bristol, Brighton, Kent and even Vienna, Austria as well as London.
From the Edible Bus Stop, Herbal High Road and Gin Garden to a knit your own garden event, National Trust David Attenborough Days for youngsters and a ‘human planting’, Chelsea Fringe is mix of pop-up gardens, art installations, community happenings and talks and demonstrations.
Conceived as a complementary event to The RHS Chelsea Flower Show but an independent venture, Chelsea Fringe attracted 45,000 visitors last year.
Most of this year’s events are free to visit and locations including Covent Garden piazza, the Inner Temple and Battersea Power Station, which will be open to the public for free for the first time in decades.
Launching the festival at Battersea Power Station on Friday, Chelsea Fringe founder Tim Richardson said:"Chelsea Fringe burst out of the Chelsea Flower Show and reaches all those parts of London that Chelsea Flower Show does not reach. It reaches futher than London - Tehran was interested at one point."
He spoke about reaching "a new generation of gardeners" and added "Chelsea Flower show is haute couture and we are street fashion. We are all about openness and freedom."
To be added to the Chelsea Fringe programme, projects need only be interesting, legal and about gardening, gardens, plants or landscapes. Participants can register until the end of the festival on 9 June.
