Elena Taro (Colocasia ) The Elena Taro has large, 20" lime-green leaves with bold red-purple veining. Makes quite a statement when planted with several in a row or in pots on your deck or patio! Place Elena Taro in your pond as a magnificent focal point. (When planting in your water feature, use planting baskets or pots with holes, as the roots need oxygen to flourish.) Taro needs warm water to thrive and helps to take up extra nutrients in the pond through their roots, thus helping to reduce algae. Plant in sun to part shade and enjoy all summer long. When planting in containers, add shorter plants in front to accent the veining in the leaf! Grows 3' tall. Bulbs are tender and must be overwintered indoors.Plant in spring after all danger of frost has passed and lift after first frost in the fall.
