Hard to miss in the garden, Colocasia (Taro or Elephant Ears) can be deciduous or evergreen, tuberous perennials with dramatic, large, arrow-shaped or rounded leaves. Ranging from bright green to deep purple or black, the leaves are often adorned with exquisite veining or variegation. Forming an impressive accent, they add an exotic touch to mixed perennial borders, aquatic gardens or containers. Most plants are hassle-free and create a compelling backdrop for most plants. They are definitely worth a try.
