Sweet corn
Zea mays var. saccharata (botanically a grain)
Distinctly sweet when fresh-picked; starch-sugar conversion at picking causes rapid sweetness decline; corn within hours of picking is dramatically sweeter than 2-day-old corn.
About Sweet
Sweet corn — botanically a grain (Zea mays), culinarily a fresh summer vegetable — is the quintessential American summer crop. Fresh corn on the cob defines summer cookouts, July 4th celebrations, and Midwestern corn-belt cuisine; sweet corn distinguished from field corn (grain corn) by the cultivar's higher sugar content, picked at the immature 'milk stage' when kernels are sweet and tender rather than dried for grain processing. The encyclopedia includes sweet corn as a boundary case — it occupies vegetable culinary contexts despite its grain botanical classification (paralleling the inverse for tomatoes and peppers). Genuine peak season is roughly 4-6 weeks in mid-summer when corn is harvested locally and eaten within hours; the sugar-to-starch conversion that begins at picking dramatically reduces sweetness over days.

Editorial notes
Locally-grown corn within hours of picking is dramatically sweeter than corn shipped over days. The 'farm-to-table' concept matters more for sweet corn than for almost any other vegetable.
