Pisum Sativum
The pea is most commonly the small spherical seed or the seed-pod of the pod fruit Pisum sativum.
Each pod contains several peas, which can be green or yellow. Botanically, pea pods are fruit, since they contain seeds and develop from the ovary of a (pea) flower. The name is also used to describe other edible seeds from the Fabaceae such as the pigeon pea (Cajanus cajan), the cow pea (Vigna unguiculata), and the seeds from several species of Lathyrus.
P. sativum is an annual plant, with a life cycle of one year. It is a cool-season crop grown in many parts of the world; planting can take place from winter to early summer depending on location.
The average pea weighs between 0.1 and 0.36 gram.
A pea is a most commonly green, occasionally golden yellow, or infrequently purple pod-shaped vegetable,widely grown as a cool season vegetable crop.
Peas have both low-growing and vining cultivars. The vining cultivars grow thin tendrils from leaves that coil around any available support and can climb to be 1–2 m high. A traditional approach to supporting climbing peas is to thrust branches pruned from trees or other woody plants upright into the soil, providing a lattice for the peas to climb. Branches used in this fashion are sometimes called pea brush.
Metal fences, twine, or netting supported by a frame are used for the same purpose. In dense plantings, peas give each other some measure of mutual support. Pea plants can self-pollinate.
