The three faces of peas--fresh peas, dried peas, and edible-pod peas--are different enough that it is hard remembering they are all the same thing, peas, Pisum sativum (pea family, Fabaceae).
Mostly, when we say "peas" today, we are thinking of shelling peas (garden peas, English peas) especially ones that have been frozen, since peas freeze really well and season for fresh peas is short.

Peas dry relatively easily, store well and are high in protein and vitamins B and C. In addition they contain no toxins and don't cause allergies. They are also bigger than most other seeds available in ancient Eurasia. With all that going for them, it is no surprise they became a staple food.
The seeds can be green, brown, white, yellow or blue when dry. Dried peas can be ground into powder to make a flour.
As a common food plant, peas accumulated specific terms and folklore. Pea was only one of the English names given the plant in the 16th century. Thomas Hill in The Gardeners Labyrinth, the first English-language gardening book, mainly called them peason, sometimes pease or peas. (Hill's book is wonderful for its unstandardized spelling. Hill spells the same word differently on the same page.) The word "pea" is a late addition to English. Apparently people were bothered by a singular that sounded plural: "You dropped a pease" and created a new singular "pea".
Other old terms used with peas include cosh, pescod and squash. You cosh peas to shell them which takes the peas out of the cosh. Shakespeare refers to a pea pod as pescod and an unripe pea pod as a squash. Both psecod and squash were insults if applied to a person.
A European folk remedy used peas to be rid of warts. For each wart, you wrapped a pea in paper and buried it, saying "As this pea shall rot away, so my warts shall soon decay."
Pease porridge hot;
Pease porridge cold;
Pease porridge in the pot,
Nine days old."
The rhyme goes back to the Middle Ages, and refers to what we would today call pea soup. I remember being puzzled by it, not knowing the word porridge or why it would be nine days old. Another virtue of peas is that a pot of old porridge would still be nutritious and reasonably tasty.

Edible-pod peas, called snow peas or sugar snap peas, are even more recent. Some were grown in the early 17th century but only since 1979 were modern varieties were developed and promoted.
Production of peas is the fifth largest of the world's legumes, behind soybeans, common beans, peanuts and chickpeas. In addition to their uses as food, peas are often incorporated in animal fodder.

And of course, peas are availabe for diverse puns.
Let me wish you:
|Peas on Earth|
This pun and holiday wish is in remembrance of Tim Myers, who taught it to me, and shared it with someone new every Christmas season.
