Landscape Attributes

Giant Elephant Ear is an open herbaceous annual with a shapely form and gracefully arching foliage. Its wonderfully bold, coarse texture can be very effective in a balanced garden composition.

This is a relatively low maintenance plant, and should be cut back in late fall in preparation for winter. It has no significant negative characteristics.

Giant Elephant Ear is recommended for the following landscape applications;

  • Accent
  • Mass Planting
  • General Garden Use
  • Container Planting

Planting & Growing

Giant Elephant Ear will grow to be about 9 feet tall at maturity, with a spread of 12 feet. Although it's not a true annual, this fast-growing plant can be expected to behave as an annual in our climate if left outdoors over the winter, usually needing replacement the following year. As such, gardeners should take into consideration that it will perform differently than it would in its native habitat.

This plant does best in full sun to partial shade. It is quite adaptable, prefering to grow in average to wet conditions, and will even tolerate some standing water. It is not particular as to soil pH, but grows best in rich soils. It is somewhat tolerant of urban pollution. This species is not originally from North America. It can be propagated by division.

Giant Elephant Ear is a fine choice for the garden, but it is also a good selection for planting in outdoor pots and containers. Because of its height, it is often used as a 'thriller' in the 'spiller-thriller-filler' container combination; plant it near the center of the pot, surrounded by smaller plants and those that spill over the edges. Note that when growing plants in outdoor containers and baskets, they may require more frequent waterings than they would in the yard or garden.
