Elephant ear

Commonly used as a Houseplant

ELEPHANT EAR are tropical foliage plants with large dark green leaves. In USDA plant hardiness zone eight and above, elephant ears can be left outside year-round. They are not native to Florida but have become naturalized in some wetland areas in the southern half of the state and are widespread.In cold climates, the plants are treated as annuals, providing an infusion of tropical landscaping, albeit short-lived. But they can be brought indoors for winter to extend their lives. 

In USDA Hardiness Zones 7 to 11, elephant ears can be left outside year-round and are treated as perennials. In colder climates, they are typically treated as annuals and discarded at the end of the growing season. However, you could also dig up the tubers after the first fall frost, store the tubers indoors, and replant them next year after the last spring frost.
