Costus villosissimus - a tall and very hairy Costus from South America and the Caribbean Islands.
It is easily recognized by its extremely hairy stems and leaves and long stiff hairs that have given it the name "porcupine ginger."
It grows quite tall, to 8 or 9 feet in the tropics, and the terminal flowers are gorgeous, a soft pure yellow against green appendaged bracts.
