Elephant ear plant (Colocasia) in Louisiana. (16 pics)

Cut the foliage back to about a couple of inches (5 cm.) after the first frost in your area and then carefully dig up the plants. Allow the tubers to dry out for about a day or two and then store them in peat moss or shavings. Place them in a cool, dark area such as a basement or crawlspace. Container plants can either be moved indoors or overwintered in a basement or protected porch.
