Hard to miss in the garden, Alocasia (Elephant Ears) are robust evergreen rhizomatous or tuberous perennials with dramatic, large, arrow-shaped leaves. Standing upright (unlike those of Colocasia), they are so breathtaking, it is as if one plant could bring all the green in the world. Forming an impressive accent, they add an exotic touch to mixed perennial borders or containers. Most are hassle-free and create a compelling backdrop for most plants. They are definitely worth a try.
