Colocasias are tropical looking perennial plants known in the western world as elephant ear plants or taro.

Colocasia culture is fairly simple. Just remember the mantra: "more water + more nutrients = more elephant ear." Elephant ears are heavy feeders and for best performance require organic fertilizers and rich organic soil with plenty of composted material. A pH from 5.5 to 7.0 is satisfactory. Most prefer bright sunlight, unless grown in extremely hot, low humidity climates, where some light shade will be necessary.
