Marks & Spencer is exclusively stocking the vegetable, which will be available until November.
As Grower reported (1 September), Chinn has been developing the production system - based on the discovery of a variety that can grow in the UK climate at this time of year - for several years.
M&S agronomist Dr Simon Coupe said: "We went on several study trips with our grower, who travels the world researching asparagus, and in the Mediterranean we discovered a special new variety that we thought could grow in the UK.
"We then worked out a careful plan for feeding and watering it so it could grow in the UK during the autumn to enable us to deliver a second season of delicious British asparagus."
Chinn, of Cobrey Farms in Herefordshire, added: "This new variety will revolutionise the asparagus industry by offering British-grown asparagus to M&S customers for a further two months, long after the traditional season has finished.
"We really want to drive the British industry forward and to do this in the most sustainable and natural way."
