For bold foliage and a dramatic display, there is no better choice than elephant ears, or Colocasia. The large heart-shaped leaves grow in gorgeous tones of emerald, purple, black, chartreuse and yellow. Their big size and fantastic hardiness makes them ideal for solving bare, hot, or moist spaces. Try Planting Elephant Ear Bulbs as a border, using them in big pots, or combining these versatile jewels with other tropical foliage plants. Different varieties of the species naturally work well together, and placing them en masse is an easy way to have an impressive array year after year.
