Sunlight bouncing off vibrant colour from the UK's largest commercial outdoor tulip crop is difficult for artist Nigel Dickerson to resist.

Each spring, for nearly a decade, Mr Dickerson has painted the tulip fields near King's Lynn - drawn to them by the "beauty of colour and the beauty of the space" they provide, he said.

The flowers, from Belmont Nurseries, are grown as a bulb crop.

This means they will never make it to a vase - they are beheaded to ensure the bulbs are strong enough to "force" flowers to grow under glass out of season to supply supermarkets.
