The leaves will grow taller than an average size human and possibly as big as a small car! Gunnera Plant is deciduous, meaning it will die back to the ground in the winter and come back in the spring. Also the stalks are edible with a taste similar to rhubarb. The plant can tolerate sunny or shaded conditions. Gunnera is native to Southern Chile. Zone 7-10.
