Introduction
The upright, multiple, unbranched stems of corn plant, with rosettes of arching, broad evergreen leaves have a wide, central yellow stripe, and form a heavy but graceful tropical clump, suitable for low-maintenance container culture or specimen planting. Mass plant on two-foot centers for a coarse textured, clumping effect. Extremely fragrant flowers are occasionally produced and open during the night.

Use and Management
Corn plant requires shade and is tolerant of drought and a wide variety of soil types, though preferring an organic soil. Do not overwater as root rot can cause plant death. The cane of the corn plant is usually cut into various lengths and rooted into a container in the nursery. Two to several stems grow from the top of the cane cutting, creating a multiple head of foliage. Individual leaves can last several years on the corn plant.
Propagation is by tip cuttings.
Pests and Diseases
Mites, thrips, and chewing insects are a problem.
Corn plants are sensitive to leaf spot diseases and root rot.
