Description: The Congo Green is a unique tropical plant native to South America. This plant is different than most philodendrons as its stems will not grow in a vine like habit. The Congo Green is a self-header that spreads outward as it grows upward. The glossy, dark green, thick leaves are spaced very close to each other on a single stem. The stiff, barely visible stem, keeps a Philodendron Congo upright and elegant looking as it matures.
