Waitrose has pledged to stock only English raspberries this season and is exclusively stocking a new variety, Octavia.
A spokesman said: "We want to sell as much British produce as possible. If the quality is there and the season is right and there's enough of it, we want it on our shelves."
As well as Octavia, the retailer will also be stocking new variety Himbotop, introduced to the UK by grower Rob Simpson from Switzerland.
Traditional offerings of Tulameen, Glen Ample, Joan Squire and Autumn Bliss will also be on sale throughout the season which ends min-August.
