Pisum sativum var. sativum – pisum means pea; and sativum means cultivated, in Latin.
One of the most ancient old-world vegetables, the garden pea can be traced to the Bronze Age. It was domesticated in Europe and later in southern Russia, Armenia, northern India, Pakistan and the mountains of Ethiopia. Primitive peas were found in the city of Troy. This vegetable reached China early in the Tang Dynasty, 600 to 900 BCE.
