Upright, strong, robust stalks produce smooth strap-like leaves. Pointed-tipped leaves are up to 36 in (90 cm) long. Feathery male flowers come in terminal panicles, while female flowers come in heads up to 8 in (20 cm) long, originating from leaf axils, and packed with yellow, white, or black shiny grains, up to 10 mm across, all enclosed within the leaves. These are known as "ears" of corn.

More information about this species can be found on the genus page.

The susceptibility of maize to the European corn borer, and the resulting large crop losses, led to the development of transgenic expressing the Bacillus thuringiensis toxin. "Bt corn" is widely grown in the United States and has been approved for release in Europe.
