The Chelsea Flower Show: A blooming lovely day

The sun is shining and the flowers are blooming in Britain's most prestigous flower show.

Underway this week, the Chelsea Flower Show is taking place in the grounds of the 17th-century retirement home for army veterans, the Chelsea Hospital. Formally known as the Great Spring Show, this year's event also features an exhibition of photographs of the Queen attending over the years, in tribute to this year's Diamond Jubilee. 

Check out the best shots of the extravagant gardens and their visitors in the glorious sunshine.
