As Olympic fever heats up, and with only 100 days left until the start of the 2012 games, Kew Gardens has unveiled its own nod to the impending events.

The royal botanical gardens revealed an inventively planted slew of pansies, violas and apple mint flowers on Wednesday, April 18, that had all been carefully arranged into the shape of the Olympic rings.

Fifty metres long and visible from planes flying overhead, some 20,000 plants were used to recreate the iconic rings.

Sourced from UK growers, 4,000 were used for each ring, with bold colours achieved using harmless coloured mulch and sturdy coloured resin pathways created so visitors can walk through the rings themselves.
