International Garden Photographer of the Year 2011 winners

The winner of the International Garden Photographer of the Year 2011 title and the £5,000 prize for the best single image is UK-based photographer Colin Roberts for Sea Thrift Flowers. His picture depicts Widemouth Bay in Cornwall, as a beautiful sunset streams across the sea view, illuminating the flowers in the foreground. Colin’s winning photograph was chosen from the Wildflowers category.

Contest judge Clive Nichols said: "This image struck me immediately - the depth of field is superb, leading the eye from the beautifully backlit flowers in the foreground all the way to the sea on the horizon, giving a great sense of depth to the picture and placing the thrift in context."
