Dark star is a cross of four different varieties of elephant ear, selected with the goal of creating a hybrid that combines impressive size with improved cold tolerance. Dark star delivers. It can reach 6 feet high, with leaves up to 5 feet wide. For added drama, the deep purple of the stem is continued in the purple veins of each leaf.
While it's not cold hardy in our climate here, it can tolerate temperatures down to about 15 degrees, which is unusual for a plant of tropical origin. Just give it full to part sun, even moisture, and plenty of room to grow.
Note: All elephant ear plants can be toxic to pets, and poisonous to humans if eaten.
