Pilea cadierei Aluminum Plant1

Edward F. Gilman2


The variegated foliage on aluminum plant is unlike any other, with shiny silver, irregularly shaped markings parallel to the lateral veins (Fig. 1). Leaves are held opposite each other on square, green stems, producing a thick ground cover about 12 inches tall in a shaded landscape. Small, white flowers are produced at the ends of the stems in the summer, but they are mostly overshadowed by the conspicuous foliage.

Use and Management

Aluminum plant forms a thick ground cover within 2 years after planting on 18-inch centers. Unrooted stems can be struck into the ground and will root if kept moist in a shaded location. You can propagate the plant quickly in this manner. Locate the plant in a fully shaded location since foliage on aluminum plant will discolor in the sun. Provide for irrigation in dry weather and fertilize regularly to keep the plant thick and looking nice.

Pests and Diseases

Mites can spoil the foliage in hot, dry weather. Locate in the full shade to prevent this.
