This summer The Royal Parks is hosting 11 events across six parks.
They include the triathlon and 10 km swimming competitions in Hyde Park, the modern pentathlon and Olympic and Paralympic equestrian events in Greenwich Park, cycling road race events passing through Richmond Park and Bushy Park and the beach volleyball at Horse Guard’s Parade Ground in St James’s Park.
Regents Park assistant park manager Mark Bridger said: "The Royal Parks are very proud to be such an important part of the London 2012 Games. The Regent’s Park, though not a host venue like some of our sister parks, wanted to reflect this exciting summer. When one of the team, Martin Moore, inspired by Team GB came up with the floral Union Jack design, we went with it.
"The red, white and blue display is made up of Lobelias, Salvia, Begonias, Heuchaeras and Verbenas. We are completely behind the team and when the pressure of international competition is over we hope athletes visit the park for some well earned relaxation."
