Introduction
Beautifully marked leaves in various shades of green, cream, white, pink, and silver held aloft on maroon stems make peacock plant an attractive, clump-forming plant for outdoor use or as a house plant. The undersides of the leaves are dark purple making a striking contrast to the lighter colored tops of the leaves. Flowers are small and inconspicuous to all but the astute observer. The striking foliage gives this plant distinction.

Use and Management
A porous potting media high in organic matter is preferred for best leaf color and growth but avoid constantly wet soil as root-rots are quite damaging. Filtered light is needed as bright light will wash out the brilliant leaf colors. High humidity is vital for growth as a house plant, with daily mistings recommended. Plant on three-foot centers for mass planting outdoors. Peacock plant also works well as a tall ground cover toward the front of a shrub border. It performs well in a container on a deck or patio in the shade.
Propagation is by cuttings or division.
Pests and Diseases
Mites can be a serious pest problem, particularly if the plant is in a sunny location.
No diseases are of major concern.
