Field pea The field pea is a type of pea of the species ''Pisum sativum'', sometimes called ''P. sativum'' subsp. ''arvense'' (L.) Asch. Also known as dun (grey-brown) pea, Kapucijner pea, or Austrian winter pea, field peas are one of the oldest domesticated crops, cultivated for at least 7,000 years. They are now grown in many countries for both human consumption and stockfeed. There are several cultivars and colors including blue, dun (brown), maple and white. The field pea should not be confused with the Cowpea (''Vigna unguiculata'') which is sometimes called the "field pea" in warmer climates.〔(【引用サイトリンク】url=http://www.pulseaus.com.au/Fieldpea.aspx )〕 ==Description== It is closely related to the garden pea, whose immature pods and seeds are used throughout the world as green vegetables. It is a climbing annual legume with weak, viny, and relatively succulent stems. Vines often are 4 to 5 feet long, but when grown alone, field pea’s weak stems prevent it from growing more than 1.5 to 2 feet tall. Leaves have two leaflets and a tendril. Flowers are white, pink, or purple. Pods carry seeds that are large (4,000 seeds/lb), nearly spherical, and white, gray, green, or brown. The root system is relatively shallow and small, but well nodulated.
