Alocasia spp. Elephant's Ear

Edward F. Gilman, Ryan W. Klein, and Gail Hansen


The Alocasia genus contains a variety of showy, large-leaved, tropical plants, some with colorful leaves. There is a wide variety of leaf sizes, color, and variegation among species. Elephant's ear gives a bold tropical effect to the landscape with its unusually large, shield-like, fleshy green leaves. They perform well as accent plants, but some selections grow very large. For this reason, only one or two of these large-leaved types are needed in most residential landscapes. Of course, more can be used if the smaller selections are planted. The smaller-leaf types can be planted in mass as a ground cover for a rich, tropical effect, or they can be used to edge or border a walk or patio. Most are well adapted for container gardening.

Use and Management

Performing best in rich, moisture-retentive soil in full sun or shade, elephant's ear will require little attention once established. Many selections grow well in soggy soil and some will invade these areas forming dense thickets. The tender leaves are subject to wind damage but do not have any major pest problems. Freezing temperatures kill the foliage, but in USDA hardiness zone 8b and south the plant grows from the base when warm weather resumes.

Design Considerations

The large, medium-green leaves and lush, leafy, irregular form of the elephant's ear will give the landscape a cool, tropical feel. The mass of leaves with pointed tips and rippled edges creates a coarse texture, and the light and dark shadows within the cluster of leaves emphasize the coarse texture. Pair with plants that are softer with small foliage and mounding or spreading forms, or grasses with thin, strappy blades and wispy flowers. Yellow-green, variegated green, and/or burgundy foliage in the companion plants will highlight the deep green of the leaves. When pairing with other flowering plants use white and/or warm colors such as pinks, light corals, soft yellows, and light orange to contrast the deep green.

Pests and Diseases

There are no major pest problems.
