Metal fences, twine, or netting supported by a frame are used for the same purpose. Along with broad beans and lentils, these formed an important part of the diet of most people in the Middle East, North Africa and Europe during the Middle Ages. In modern times peas are usually boiled or steamed, which breaks down the cell walls and makes the taste sweeter and the nutrients more bioavailable. Updates?

The seeds may be planted as soon as the soil temperature reaches 10 °C (50 °F), with the plants growing best at temperatures of 13 to 18 °C (55 to 64 °F). Uses. Mendel chose peas for his experiments because he could grow them easily, develop pure-bred strains, protect them from cross-pollination, and control their pollination. Pisum sativum elatius. (2016). sativum is part of the family of legumes known as the IRLC or the Inverted Repeat-Lacking Clade.

Legumes contain at least 20 percent protein, and they are a good source of most of the B vitamins and of iron. The popularity of green peas spread to North America. Beans and peas are the seeds of leguminous crops that are able to utilize atmospheric nitrogen via parasitic microorganisms attached to their roots. Results. The plants are fairly easy to grow, and the seeds are a good source of protein and dietary fibre. Flowers are white, pink, or purple. The weevil larvae feed on the root nodules of pea plants, which are essential to the plants' supply of nitrogen, and thus diminish leaf and stem growth. The next step is blanching. , It is a climbing annual legume with weak, viny, and relatively succulent stems. New England Distribution and Conservation Status. Research suggests that both P. sativum and P. fulvum were domesticated in the Near East about 11,000 years ago, likely from P humile (also known as Pisum sativum subsp.  Despite its scientific popularity, its relatively large genome size (4.45Gb) made it challenging to sequence compared to other legumes such as Medicago truncatula and soybeans. , A variety of diseases affect peas through a number of pathogens, including insects, viruses, bacteria and fungi. The pea was also present in Georgia in the 5th millennium BC. The fruit is a pod that grows to 10 cm (4 inches) long, splitting in half when ripe. Farther east, the finds are younger.

Modern split peas, with their indigestible skins rubbed off, are a development of the later 19th century.  Unless otherwise noted these are so called dwarf varieties which grow to an average height of about 1m. Each pod contains several peas, which can be green or yellow. Sodium bicarbonate is sometimes added to soften the peas. For other uses, see, Species of flowering plant with edible seeds in the family Fabaceae. In the mid-1800s, peas in a monastery garden in Austria were famously used by the monk Gregor Mendel in his pioneering studies of the nature of heredity.  The immature peas (and in snow peas the tender pod as well) are used as a vegetable, fresh, frozen or canned; varieties of the species typically called field peas are grown to produce dry peas like the split pea shelled from a matured pod.

Thomas Jefferson grew more than 30 cultivars of peas on his estate. Vines often are 4 to 5 feet (120 to 150 cm) long, but when grown alone, field pea’s weak stems prevent it from growing more than 1.5 to 2 feet (45 to 60 cm) tall. The vining cultivars grow thin tendrils from leaves that coil around any available support and can climb to be 1–2 m high. It is in flower from May to September, and the seeds ripen from July to October. ... Catalogue of the Vascular plants of New York state Memoirs of the Torrey Botanical Club 27: 1-542.
