Rhubarb is a vegetable that originated from Western China, Tibet, Mongolia, and Siberia. Ben Franklin is credited with bringing rhubarb seeds to America. By 1829, rhubarb seeds were being sold in garden catalogs. It is a member of the buckwheat family. Only the stalks of the rhubarb are used, possibly because people think the leaves and roots contain oxalic acid and other unknown poisons. Frostbitten stalks are also avoided since they can also be toxic. A common folk name for rhubarb is "pie plant." Rhubarb is considered to be a harbinger for spring since harvesting can begin in April.
