For maximum-impact foliage, nothing compares to the gargantuan leaves of colocasia esculenta (also known as elephant ear)! Growing several feet (not inches, FEET) wide and long, these leaves add a primordial, prehistoric feel and serve as excellent conversation starters! Hardy to about zone 7, in most gardens elephant ear needs overwintering: store the bulb in a cool, dry, and dark place, and re-plant them every spring to watch the massive leaves get reborn.
