Rhubarb (Rheum rhabarbarum) is a species of plant in the family Polygonaceae that are herbaceous perennials with large somewhat triangular leaves and long fleshy stalks. Rhubarb stalks are tart and are often paired with sweet ingredients and commonly used in pies, sauces and pastries. The roots and leaves are inedible owing to the high content of oxalic acid and possibly another unidentified toxin. Rhubarb varieties are mainly red, but also come in pink and green stalks. The redder the stalk, the sweeter the rhubarb is.rhubarb
