Alocasia ‘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.
If you’re looking for an outdoor plant, it can tolerate temperatures down to about 15 degrees, which is very unusual for a plant of tropical origin. Just give it full to part sun, even moisture, regular fertilizer, and plenty of room to grow.
