Thaumatophyllum bipinnatifidum (common names: split-leaf philodendron, lacy tree philodendron, selloum) is a plant in the genus Thaumatophyllum, in the family Araceae. Previously it was classified in the genus Philodendron within subgenus Meconostigma. The commonly used names Philodendron bipinnatifidum and Philodendron selloanum are synonyms. This plant is native to South America, namely to Brazil, Bolivia, Argentina, and Paraguay, but is also cultivated as a landscape plant in tropical, subtropical and warm temperate climates. Thaumatophyllum bipinnatifidum is a tropical plant that is usually grown in full sun, but can tolerate and adapt to deep shade. It grows best in rich, moisture-retentive soil that can be slightly alkaline. This plant is greatly known for its ease in covering a land mass, and typically spread out its tree-like trunk from anywhere between eight and ten feet.
