Colocasia 'Black Runner' is a first cousin and probably a mutation of the popular Colocasia 'Black Magic'. Colocasia 'Black Runner' makes a stunning 5' tall clump with 2' long leaves that emerge more of a black-purple than Colocasia 'Black Magic'. Its leaf edges are also much more ruffled than its cousin. The biggest difference, however, is the black, snake-like runners creeping along the ground, pegging into moist soil every few inches and sending up another plant. This is a superb new introduction that will soon find its way into gardens around the world. As with most elephant ears, moist soil and high nutrition are the keys to great specimens.
