Tree Philodendron. Large semiwoody shrub FROM Brazil with enormous glossy leaves, and a single erect unbranched stem that tends to fall over and sprawl when the plant gets large. The robust stem bears stout aerial rootlets between conspicuous leaf scars. The leaves are up to 3' long, deeply dissected into many wavy-margined lobes, and held on long petioles. Older and larger plants develop leaves that are more deeply dissected and more ruffled. The inflorescence consists of a foot-long purplish red spathe enclosing an upright spadix with many tiny petalless flowers. In Nature, tree philodendron can get as large as 15' tall and 15' wide with a stem 6" or more in diameter. It is a popular houseplant if you have enough room, and is great for office interior design, etc.
