It's the last full week of May and on the horticultural calendar that can only mean one thing – the worlds most prestigious flower show, RHS Chelsea, is in full swing.

But running parallel to the show is the Chelsea Fringe Festival, RHS Chelsea’s lesser known (but growing in popularity), slightly rebellious cousin.

The fringe is now in its sixth year and runs for a fortnight from May 20 to June 4.

Tim Richardson, Chelsea Fringe Founder, Director and Telegraph Garden Writer previously described the festival as “street fashion whereas the Chelsea Flower Show is haute couture.” And with alternative, artistic garden workshops, installations, events, exhibits, talks and walks across a host of different venues, he was right en pointe with that statement.

Unlike the Chelsea Flower Show, project entry to the Fringe is open to anyone and everyone whether professional or amateur and almost anything goes as long as its legal and horticultural.

The Fringe doesn't get the same tv coverage as the Chelsea Flower Show so here’s a little taster of what's on offer this year.

Growing Edibles in Six Inches of Soil – This workshop run by Wendy Shiilam takes place on her rooftop plot in central London, five minutes from Oxford Circus.

It’s such a small plot, visits are by appointment only but it will be unmissable for occupants of the big smoke who are interested in growing edibles in small, urban spaces.

The Inner Temple Dog Show Returns: celebrating the bond between gardener and dog – If I was still living in London, this is one fun event I wouldn’t want to miss.

A combination of two things I hold dear – my dog and my garden. The Inner Temple Garden is one of the largest gardens in the City of London and probably oldest, having been in cultivation since the 12th century.

The Dog Show is open to all dogs and is spread across five categories: publics favourite, dog with the waggiest tail, best junior handler, best floral outfit (dog and handler) and garden agility.

Little Shop of Horrors – An outdoor screening of the 1986 rock musical horror comedy ‘Little Shop of Horrors’ is preceded by a short talk on carnivorous plants. Not very high on the list of many peoples ‘interesting plants list’, carnivorous plants are beautiful and fascinating and this film is an oldie but a goodie.

The Guerilla Gardeners Garden Tour - Guerrilla Gardening has been at the heart of the Chelsea Fringe since its inception 6 years ago so this is a tour you’d want to join.

Richard Reynolds has been guerrilla gardening (gardening without permission) on the south bank for thirteen years and his work has attracted international attention, inspiring others across the country and globe to make over neglected urban spaces. Richard guides the tour around some of his guerrilla gardens and talks in depth about how he pulls off his gardens in the captial. An inspiring walk and talk from a respected gardening vigilante.
