Planting & Growing
Regal Shields Elephant's Ear will grow to be about 6 feet tall at maturity, with a spread of 4 feet. It has a low canopy with a typical clearance of 2 feet from the ground. It grows at a medium rate, and under ideal conditions can be expected to live for approximately 5 years.
This plant should be grown in a location that is shaded from the hot afternoon sun. 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 particular variety is an interspecific hybrid, and parts of it are known to be toxic to humans and animals, so care should be exercised in planting it around children and pets.
Regal Shields Elephant's Ear is a fine choice for the garden, but it is also a good selection for planting in outdoor pots and containers. With its upright habit of growth, it is best suited for use 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. It is even sizeable enough that it can be grown alone in a suitable container. Note that when growing plants in outdoor containers and baskets, they may require more frequent waterings than they would in the yard or garden.
