Common domestic corn. The corn plant often grows to 3 m in height, though some natural strains can grow 12 m. The stem is commonly composed of 20 internodes of 18 cm length. A leaf, which grows from each node, is generally 9 cm in width and 120 cm in length. Ears develop above a few of the leaves in the midsection of the plant, between the stem and leaf sheath, growing to a length of about 18 cm with 60 cm being the maximum.
Can occasionally be found in the wild when transported by birds/animals from bird feeders. Domesticated corn is very different in appearance from the true native corn, which has much smaller ears.
