Var. Black Runner: a superb Colocasia and a must for black plant fanatics. Large matt black, heart shaped leaves up to 20" long, on black/purple leaf stalks. As with most elephant ears, moist soil and high nutrition are the keys to great specimens. Grow in rich, fertile moisture retentive soil or as a pond marginal in full sun for darker leaves. Note that in shade leaves turn dark green. Once moved to bright sun, they turn back to black. In cooler subtropical climates leaves die back and the plant emerges from a rhizome in spring.
Var. Mojito: This new sport of Colocasia was discovered in Florida. Incredible contrasting blacks and greens adorn its leaves. This camouflage effect is matched with light green stems streaked with dark purple that fade up to pink, with chartreuse highlights mixed in to create a totally wild and exotic scene in the summer garden. No two leaves are the same. Even the stems are highlighted with stripes. Grows more compact than other Elephant Ears, making it an excellent choice for a large container.
