The carrots have all been grown by Bartletts of Norfolk. According to technical manager Steve Warwick: "We know that different coloured varieties of produce are popular with shoppers and we worked with Tesco on developing a range of carrots using seeds from uncommon types."
The carrots will also benefit from the latest harvesting technology, he added. "Our new machinery can pull the carrots out of the ground, wash them and bag them all within one minute.
"We can then have the carrots in stores inside 12 hours, which shaves a good 12 hours off the existing field-to-store times."
