The Rings, which are 50m long and 15.5 metres each in circumference, are made up of a total of 20,000 plants and are visible from the Heathrow flight path.
The flowers were planted over a period of five days by a team of volunteers and Kew staff and consist of Pansy ‘Light Blue’, Viola ‘Clear Yellow’, Viola ‘Black Delight’, apple mint (Mentha suaveolens) and Viola ‘Red Blotch’ plants. They will be in full flower for the summer.
Standing in the Rings are athletes' families, torchbearers, Games Maker volunteers, London 2012 Festival participants and schoolchildren - all getting ready to welcome the world in the summer.
