The Dracaena genus of tropical broadleaf evergreen shrubs and trees includes several species commonly used as houseplants throughout the world. There are many types of dracaena houseplants to choose from, most of them have spear- or grass-shaped leaves that extend off one or more thickened, cane-like main stems. Dracaena are easy to grow. While they thrive in bright, indirect light, they even qualify as low-light houseplants.
