The long trunk is typically thin when young, and becomes more bulbous when mature. Madagascar palms in their original habitat can reach 20 feet in height but usually grow to 10-15 feet tall. The trunk, which stores water for conservation, is mostly light gray. Parts of it will turn green so that it can photosynthesize during the growing season. Another way the plant has adapted to drought is through its long, two-inch thorns that cover the entire stem.
