Species overview
About the Corn
Corn, also called maize, is a cultivated grass. Tassels grow at the top, while ears develop along the stem inside leafy husks. The kernels on an ear are its grains.
Corn connects Costa Rican farms with tortillas and other traditional foods. Different varieties produce different kernel colors and growing habits; one yellow ear does not represent every kind of maize.
Identification
Key Features of the Corn
Tall grass with broad leaves along the stem
Tassels at the top
Ears wrapped in husks along the stem
Silks emerging from developing ears
Habitat & range
Cultivated fields and family farms, including Guanacaste, Northern Plains and South Pacific.
Local observations
SEPSA production models document maize in Chorotega and Brunca. MAG material also records maize and bean farming systems in Huetar Norte. These are cultivation examples, not an exhaustive national distribution.
When to observe
Tassels, silks, tender ears and dry grain appear at different stages. Local planting schedules depend on rainfall and farm decisions.
Conservation & care
Visit farms only with permission and follow the host's instructions. Stay clear of machinery, chemical applications and working areas. Do not pick or taste plants without a responsible adult and the host's approval.
Observation activity
Locate a tassel and an ear without touching the plant. Ask which part releases pollen and which part carries the kernels.
