@tysonwalker :
Its scientific name is Calathea Lutea.
It's the largest of the Calthea family, growing 6 to 10 feet tall, leaves are around 3 feet long and about 15- 20" wide. The oval shaped leaves are broad and attractive, being gracefully held on long stems that gives this plant a tropical looking appearance. I've eaten the Panamanian tamale wrapped in one of its leaves . It is used as food wrapper.
