Dracaena fragrans, the corn plant or cornstalk dracaena, is a slow-growing African shrub or small tree grown mainly as a tough houseplant. It tolerates low light and neglect, so the key is to avoid overwatering.

About
Dracaena fragrans (cornstalk dracaena), is a flowering plant species that is native to tropical Africa, from Sudan south to Mozambique, west to Côte d'Ivoire and southwest to Angola, growing in upland regions at 600–2,250 m (1,970–7,380 ft) altitude.
How to grow it
In Africa, D. fragrans is commonly grown as a hedge plant. It is suited to frost-free climates and USDA Hardiness zones 10-11. Elsewhere, it is primarily popular as a houseplant and valued for its tolerance of a wide range of indoor conditions, from bright indirect light, to bright shade (which brings out more variegation in certain hybrids) and even deep shade (where it will have a darker green color). It is also very tolerant of neglect. The NASA Clean Air Study indicated that the plant aided removal of indoor pollutants such as formaldehyde, xylene, and toluene; however, these results were not applicable to typical buildings, where outdoor-to-indoor air exchange already removes volatile organic compounds at a rate that could only be matched by the placement of 10–1000 plants/m2 of a building's floor space.
The plant is known as "masale" to the Chagga people of Tanzania, who regard it as holy.
