Snap peas

Snap peas may taste like a timeless garden vegetable, but the familiar crisp, thick-walled pod is relatively modern. They belong to the same species as shelling peas and snow peas, Pisum sativum, rather than to a distinct wild plant with its own native homeland.

The deeper story begins in the Fertile Crescent and neighboring western Asia, where wild pea relatives grew and peas became part of early Neolithic agriculture. Those ancient peas were generally harvested for their seeds, often after drying. Over centuries, farmers selected many forms suited to different climates, harvest stages, and culinary uses.

Edible-pod peas emerged through selection for pods with little or no tough inner parchment. Snow peas are typically flat and harvested before the seeds swell, while snap peas have thicker, rounded pods that remain tender as the peas enlarge. The best-known modern sugar snap was created in the United States by plant breeder Calvin Lamborn and introduced commercially in 1979, helping establish snap peas as a recognizable market category.

Today snap peas are grown in temperate and highland farming regions worldwide, including California and Washington, as well as Mexico, Guatemala, Peru, China, and Kenya. Their popularity rests on a useful breeding achievement: the whole pod can be eaten, yet it delivers much of the juicy sweetness and satisfying bite associated with freshly shelled peas.
