The snow pea is an

edible-pod pea with flat pods and thin pod walls.[2] It is eaten whole, with both the seeds and the pod, while still unripened
.

Names

The common name snow pea seems to be a misnomer as the planting season of this pea is no earlier than that of other peas. Another common name, Chinese pea, is probably related to its prominence in Chinese dishes served in the West.[3] It is often called mangetout ("eat-all") in the British Isles, but this can apply both to snow peas and to snap peas.[citation needed]

Snow peas and

Ser. named in 1825.[6]
It was described as having very compressed non-leathery edible pods in the original publication.

The

scientific name Pisum sativum var. saccharatum Ser. is often misused for snow peas. The variety under this name was described as having sub-leathery and compressed-terete pods and the French name petit pois.[6] The description is inconsistent with the appearance of snow peas, and therefore botanists have replaced this name with Pisum sativum var. macrocarpum.[7] Austrian scientist and monk Gregor Mendel used peas which he called Pisum saccharatum in his famous experiments demonstrating the heritable nature of specific traits, and this Latin name might not refer to the same varieties identified with modern snow peas.[8]

Snow peas, along with

recessive genes known as p and v are responsible for this trait.[11] p is responsible for reducing the sclerenchymatous membrane on the inner pod wall, while v reduces pod wall thickness (n is a gene that thickens pod walls in snap peas).[13]

Pea shoots (Chinese: 豆苗; pinyin: dòu miáo) are the stems and leaves of the immature plant, used as a vegetable in Chinese cooking.[14] They are commonly stir-fried with garlic and sometimes combined with crab or other shellfish.[15]

Nitrogen fixers

As with most legumes, snow peas host beneficial bacteria,

intercropped with green, leafy vegetables that benefit from high nitrogen content in their soil.[16]

Cultivation

Snow peas can be grown in open fields during cool seasons and can thus be cultivated during winter and spring seasons.[13]

Storage

Storage of the pea with films of polymethylpentene at a temperature of 5 °C (41 °F) and controlled atmosphere with a concentration of oxygen and carbon dioxide of 5 kPa augments the shelf life, internal and external characteristics of the plant.[17]
