Several years ago, we received a shipment of Colocasia from India of which most were inferior to plants we already grew. After several years of trials, one plant stood out that we are now able to share. Colocasia 'Blackwater' is similar to Colocasia 'Fontanesii' with glossy, jet black stems rising to 6' tall. The stems are topped with glossy, dark olive-green leaves that are much darker and narrower, with a longer leaf tip than Colocasia 'Fontanesii'. It spreads rapidly via black snake-like rhizomes that lay on top of the ground.
