There’s nothing else like it in agriculture – the low wooden forcing sheds of Yorkshire’s rhubarb producers are quiet, warm and dark. As far as the eye can see, there are slender pink stalks topped with curly yellow leaves. Workers pick by candlelight – harsh light would cause the stalks to lose their colour. Caterpillars brought in on the roots are fooled into thinking it’s spring and hatch into butterflies to flutter around in the ethereal glow. Listen carefully and you can even hear the rhubarb growing. The tissue-like membrane that wraps around the leaves, a bit like a daffodil, pops when it unfurls.
These rhubarb sheds and the dozen or so farms that make up the rhubarb triangle between Leeds, Bradford and Wakefield are all that remain of a once thriving industry that began around a hundred and fifty years ago when miners from the West Riding pit villages growing a few spuds in their allotment would also sport a few sticks of ‘tusky’ - rhubarb grown under an old bucket to keep it pink and tender.
From these small beginnings developed Europe’s biggest forced rhubarb industry. The miners began by splitting a few roots, acquiring some land and building forcing sheds. Surprisingly, the unpromising setting of industrial West Yorkshire proved to be ideal rhubarb country. The night soil from thousands of privies and waste from local shoddy mills was used to fertilise the soil and provided just the right conditions the roots needed. In December they would be dug from the cold wet soil and transferred to the forcing sheds where devoid of food and light they would be watered and kept at a constant 60°F by the coal that was available and cheap.
By the 1920s there were over 200 rhubarb growers in the ‘pink patch’, an eight-mile stretch between Leeds and Wakefield. A farm might grow up to 90 tons a year and a rhubarb train ran regularly from Leeds to Kings Cross. But devastated by cheap imports from Holland and usurped by fashionable fruits from across the world, the rhubarb trade declined after the war. The number of growers dwindled and the last rhubarb train left Leeds in 1966.
But some growers, like Janet Oldroyd at Hopefield Farm and David Westwood at Thorpe Farm near Wakefield kept the faith and despite the decline in demand and rising fuel prices, they battled on. Then a few years ago chefs began to rediscover the unloved stalk, Delia cooked with it and we all started buying, cooking and loving rhubarb again.
There are still only a dozen Yorkshire growers today, but sales have recovered and the Oldroyds say they can sell all they produce which has climbed from 300 tons a decade ago to 1000 tons of indoor and outdoor rhubarb today.

Janet Oldroyd has done much to champion rhubarb. She is a leading light in the annual Yorkshire Rhubarb Festival and runs tours of the forcing sheds and in 2010 was instrumental in gaining Protected Designation of Origin (PDO) for Yorkshire rhubarb which means that only rhubarb grown in the rhubarb triangle can be called Yorkshire rhubarb.
There are lots of Yorkshire restaurants serving Yorkshire forced rhubarb during the November to March season, but these restaurants have long championed the stuff. The General Tarleton, The Star Inn at Harome, Melton’s, The Fox & Hounds, The Bruce Arms.
