Introduction to Corn Plant (Dracaena fragrans)

The Corn Plant, or Dracaena fragrans, is a beloved houseplant. It has won over plant lovers worldwide. Despite its name, this plant is not related to corn at all. It’s a tropical plant in the Asparagaceae family. This family includes asparagus and yucca.

What is a Corn Plant?

A Corn Plant is a slow-growing, evergreen shrub or small tree. It is cultivated as an indoor plant in most regions. Its long, arching leaves resemble those of corn stalks. That’s why it’s called “corn stalks.” These leaves grow in rosettes atop sturdy canes. This gives the plant an attractive, tree-like look. It can add a tropical flair to any indoor space.

Origin and Natural Habitat

Dracaena fragrans is native to tropical Africa. It is from Sudan to Mozambique. In its natural habitat, it can grow up to 50 feet tall. But, it rarely reaches such heights when grown indoors. The plant thrives in the understory of tropical forests. This explains its ability to tolerate lower light in our homes.

Why is it called a Corn Plant?

The name “Corn Plant” comes from the resemblance of its leaves to those of corn or maize plants. The long, sword-shaped leaves grow in clusters at the top of woody stems. They create a silhouette like that of a corn stalk. But, it’s a visual similarity. Dracaena fragrans is not related to corn.

Common names and varieties

Though “Corn Plant” is the most common name, Dracaena fragrans has other ones:
