The corn plant (Dracaena fragrans) is a tropical African evergreen tree famous in Europe as an indoor plant since the mid-1800s—and in the U.S. since the early 20th century. They grow slowly from thick canes or stems that produce long, narrow leaves like stalks of corn, growing upward.
They make good houseplants because they are tall and narrow, typically only reaching around 4- to 6 feet tall. However, these plants aren't high maintenance once you get their growing conditions right. Springtime is ideal for starting new plants, though you can typically pot nursery plants indoors at any time. If you have cats or dogs, pass on this plant as dracaena is toxic to both.
Corn plants do best in bright indoor locations protected against direct sunlight, drafts, and air conditioning and heating vents. These plants also prefer a high humidity environment.
You can put corn plants outdoors during the summer if they are in a sheltered, somewhat shady location. Protect them against strong winds. Bring the plant indoors once the temperatures fall into the 60s F.
