Xanthosoma sagittifolium is also known as Arum sagittifolium, arrowleaf, elephant ear or yautia. This perennial herb from the Araceae familly has large to huge leaves, and can be up to 6-9 ft (1.80-2.80 m) tall when grown in humid tropical areas.
Although of tropical origins, the roots and tubers of this plant can withstand cold temperatures down to about 14°F. (-10°C) Arrowleaf can thus be a most interesting tropical looking plant for gardeners in temperate zones. However, this plant needs a long warm season to grow correctly.
Leaves are sagittate (hence the common name : arrowleaf) and evergreen. They can be more than 6 ft (1.80 m) long, when grown in humid and warm areas. Leaf stems can be more than 8 ft (2.40 m) long in good growing conditions.
The inflorescence is made of a white-cream spadix and a spathe.
