SNOW PEA

The 'snow pea' [Pisum sativum ssp. sativum convar. axiphium] is a legume, more specifically a variety of pea eaten whole in its pod while still unripe.
It is one of the earliest-known cultivated plants, with evidence of having been cultivated in a region that is now along the Thailand-Burma border, 12,000 years ago[1].
It is speculated that the name comes from the whitish tint reflected from the pods.
As with all legumes, snow peas host beneficial bacteria, rhizobia, that fixes nitrogen in the soil -- this is called a mutualistic relationship -- and are therefore a useful companion plant, especially useful to grow intercropped with green, leafy vegetables that benefit from high nitrogen content in their soil.
