Hi Trina, the plants get enormous and cover huge areas of forest. They will go 100 ft. up trees, and crawl across the ground for long distances. The leaves may get old and die, but the colony just gets bigger and bigger.
The mature leaves will be over 3 feet long and have pinnate divisions. The flowers are stalked with several erect boat shaped hooded spathes about 9 inches long with spadix that are about 6.5 inches long. As they wither they will fall.

Here are the leaves getting larger.
