The Dracaena fragrans 'Massangeana' plant, also known as the corn plant, is made up of shiny green leaves that have a yellow streak running down the center of the leaves. Most Dracaena fragrans 'Massangeana' are grown indoors in pots and are relatively low-maintenance plants. If you want to grow the plant outdoors, however, you must live in U.S. Department of Agriculture plant hardiness zones 10B through 11. These tropical plants don't handle cold temperatures well.
