This year is a landmark year for the RHS Chelsea Flower Show. Not only is it celebrating its centenary year, but the 100-year ban on garden gnomes has also been lifted! Gnomes were by no means the most unusual garden feature at this year’s show, however, as innovative sculpture,  unusual materials and unique aesthetics have been used to create some truly memorable displays.

Other gardens have a more sombre mood, however, with many raising awareness for charities such as Arthritis Research UK and Sentebale. Throughout the show the gardeners’ incredible skill and dedication is abundantly clear, and will no doubt inspire visitors to make the most of their own green spaces at home.

Visitors who walk down Sloane Street on their way to the show this year will also notice two floral elephants on its east side, which were installed on Monday to raise awareness of Habitat for Humanity’s Animal Ark initiative. This charity project, alongside many others, will have its own garden at the 2014 show.

As for so many great London institutions, the first 100 years really are only just the beginning!

This weekend’s a corker: the Paralympic Games have arrived, St Paul’s is open late and Kings Cross is staging a festival with a truly delicious concept.

Summer Lates at St Paul’s Cathedral
Take advantage of extended opening hours and free entry at St Paul’s Cathedral on selected nights during the Paralympic Games. Sir Christopher Wren‘s English Baroque masterpiece tends to invoke hushed awe, so it’s appropriate that the Summer Lates openings are intended for quiet reflection. Guides and priests will be on hand to  explain the cathedral’s history and spiritual life, while organ notes drift around you. The cathedral floor will be open from 6pm until 9pm with a short service at 8.45pm, and the cool underground crypt will be selling “Best of British” refreshments until 10pm.
31 Aug, 3 Sep and 7 Sep

London Live at Trafalgar Square
As the Paralympic Games take the stage in the UK’s sporting summer, BT London Live has moved its site offering free London 2012 celebrations to Trafalgar Square. You’ll be able to try out Paralympic sports like sitting volleyball, wheelchair basketball and wheelchair tennis, chill out to live music or watch coverage of the Paralympics on a giant screen. It’s free entry and unticketed – just turn up.
Until 9 Sep

King’s Cross Ice Cream Festival
The organisers of the King’s Cross Ice Cream festival don’t just want you to eat the cool white stuff. They’re calling on ice cream fans to get hands on with the creative process, from milking a cow at the petting farm to experimenting with the latest nitrogen technologies to whip up some frozen delights. The festival is being held in the new Granary Square in Kings Cross and will showcase the best local ice creams from London and the South East.
1-2 Sep

Bowiefest at the ICA
The first ever festival dedicated to David Bowie’s film career will touch down at the Institute of Contemporary Arts this weekend for screenings, talks and a Bowie themed party on the opening night. Re-aquiant yourself with cult classics from the 1970s and 1980s like Labyrinth, where Bowie played Jareth the goblin king, alongside a cast of puppets from Muppets creator Jim Henson. 
31 Aug-2 Sep

Chelsea AutoLegends
Classic cars will take over Royal Hospital Chelsea‘s grounds on Sunday, as the third Chelsea AutoLegends event brings motoring fever to west London. The bill includes supercar and rally car parades and the chance to meet celebrities like five-times Le Mans winner Derek Bell. One exciting addition is the festival’s new celebration of women in motorsport, fronted by model and race driver Jodie Kidd. Another highlight will be seeing Bloodhound SCC, a car that looks like a rocket with good reason: its team are trying to break the elusive 1000mph speed barrier.

This stunning photo of the Chapel at the Royal Hospital Chelsea was shared with the Visit London Flickr group by agustinchito.

The Chapel was designed by Sir Christopher Wren who also designed St Paul’s Cathedral. You can take a guided tour given by the famous residents in scarlet coats, the Chelsea Pensioners.

The Great Pavillion contains a diverse mix of exemplary gardens: we particularly enjoyed the Trinidad and Tobago Horticulture Society’s garden, the Willams F1 display and David Austin’s spectacular roses.

Outside, vying with the temptations of Pimm’s, champagne and other delights from the catering stands, is an inspirational variety of gardens.  Much media attention has been focused on Diarmuid Gavin’s pyramid, which dominates the skyline, but we were haunted by the poignant beauty of the DMZ Forbidden Garden.
