Corn plant is a popular houseplant. Although it may grow to 20’ tall or more in its native tropical habitat in western Africa, it more often is seen in the 4-6’ tall range as a container plant in homes. Grows slowly. Rosettes of plain parallel-veined green leaves (to 2’ long and 3” wide). Over time, plants lose lower leaves revealing bare stems. Fragrant, tiny white-yellow flowers in round heads appear in terminal panicles in winter-spring. Flowers are followed by red berries. Flowers and berries rarely appear on indoor plants. D. f ‘Massangeana’ is a popular cultivar that features a wide central yellow stripe on each leaf.
No serious insect or disease problems. Watch for spider mites and scale. Leaves may brown if soils are too moist or too dry.
