Grown for its large, chartreuse-yellow, heartshaped leaves, Elephant Ear Lime Zinger adds distinctive color to the garden and gardeners often report that it seems to glow when planted with other foliage and flowering plants. The defining chartreuse-yellow leaves can reach 1.5 long with plants rising up to 3-4 tall. We have been surprised at the resiliency and vigor of this cultivar that loves hot, humid, summer weather. Native to tropical America, Xanthosomas are grown for their starchy tubers. In northern zones, the entire plant or just the underground tuber, must overwinter inside and can be replanted the following spring.
