Facts

Garden pea (Pisum sativum) is a widely cultivated plant, and hundreds of forms have been developed. Its domestication dates back at least 3000 years in southwestern Asia, and seeds have been found in archaeological sites dating back at least 6000 years. Escapes have been reported in scattered locations across North America, including New England.
