Philodendron billietiae is a hemi-epiphytic species of plant in the genus Philodendron native to Brazil, Guyana, and French Guiana. The leaves of this philodendron variety certainly put on an interesting display, especially when the plant is allowed to climb on a pole or other structure. Arrow-shaped with orange petioles and green coloration, these leaves can reach 3 feet if the plant grows in its natural habitat.
