The Story
Plant Bio
Colocasia esculenta, commonly known as taro or elephant ear, is a tropical perennial grown for its large, heart-shaped to arrow-shaped leaves. It thrives in wet, rich soils and is a staple food crop in many parts of the world.
'Big Dipper' is a unique cultivar noted for its large, upward-cupped, glaucous green leaves held on dark purple-black petioles. The leaves collect water, and as they fill, the petiole bends, pouring the water out, resembling a dipper.
