In 1893, Adam Knoblauch shipped the first field rhubarb to Seattle in gunnysacks. From there, an industry was born that exists even today. In the mid-1900s, the best rhubarb stalks were cut to size to be packed in crates for sale. Lesser quality stalks were taken to a facility in Seattle’s Georgetown neighborhood to be canned, with a lot of sugar. Photo by BartonL. Attebery, courtesy of the Ota Family.
