Why are rhubarb plants also called pie plants?
Pie Plant: My mother, born in 1902, told me that country and farm people were so poor... by the time rhubarb was ready to use, they'd depleted all of the extracts, flavorings, Watkins and Raleigh pie fillings, etc. they'd used all winter. So, Pie Plant was rhubarb, and they welcomed its growth to make their pies instead of the bought flavorings they'd used up by spring time.B. Martin
