Snow pea relationship—and are therefore a useful companion plant, especially useful to grow intercropped with green, leafy vegetables that benefit from high nitrogen content in their soil. Snow peas can be grown in open fields during cool seasons and can thus be cultivated during winter and spring seasons. Storage of the pea with films of polymethylpentene at a temperature of 5 °C and a concentration of oxygen and carbon dioxide of 5 kPa augments the shelf life, internal and external characteristics of the plant. Austrian scientist and monk Gregor Mendel used peas which he called "Pisum saccharatum" in his famous experiments demonstrating
