National Strawberry Rhubarb Pie Day is celebrated on June 9 in the United States, dedicated to the unique dessert made from a combination of strawberries and rhubarb, the latter being a vegetable. This pie is a traditional part of New England cuisine and is appreciated for its sweet and tangy flavor profile. Rhubarb, a perennial plant, is typically harvested from mid-May to early June, and while its stalks are edible and nutritious, the leaves are toxic. To observe this day, people often enjoy baking and sharing strawberry rhubarb pie, which can be made with a variety of crust styles. Additionally, some may engage in activities such as harvesting rhubarb and strawberries from local farms or even growing their own strawberries in preparation for the celebration.
