Pisum sativum
Peas range from sweet shelling peas to crisp snap peas and starchy dried peas. They are all forms of the same cool-weather crop, but with very different textures.1
In Maine, peas are among the crops sown as soon as the ground can be worked, making them one of the first annual food plants into the garden.2
That early timing follows the crop’s preference for cool weather: Maine guidance places spring sowing around workable soil and roughly 45°F soil temperature, with the best growth in the mid-50s to mid-60s Fahrenheit. Peas can also be sown for a fall crop, but heat makes germination and flowering less dependable. As legumes, they form root nodules with rhizobium bacteria and can leave some nitrogen available to a following crop when the plants are cut down.3
Fresh peas remain metabolically active after picking. They respire rapidly, consuming sugars within hours, while some of the remaining sugar is converted to starch. The familiar decline from tender sweetness toward mealiness is therefore a continuing biological change, not simply moisture loss.4
Peas prefer cool weather, roughly 55–65°F, and can be planted as soon as Northeast soil is workable. The crop is more than the familiar shelled seed: snow peas are harvested while the pods are still thin, sugar snaps when both pod and seed are plump, and tender pea shoots are edible as well.5 That makes the plant unusually generous at the table, with the pod, seed, and young vine each offering a different balance of sweetness, crunch, and green aroma. Once the seeds pass their ideal stage, their skins toughen and the starch becomes much more obvious; rapid cooling after harvest slows that quality loss.5
The distinctions among shelling, snow, and sugar-snap peas are stages of the same plant rather than entirely different foods. Snow peas are eaten before the seeds enlarge, sugar snaps when the pod and seeds are both juicy, and shelling peas after the pod has become too fibrous to eat. The tender vine tips are edible too, which makes pea one of the Northeast garden crops where pod, seed, and shoot can all become food.5
