Thaumatophyllum bipinnatifidum, commonly known as split-tree leaf philodendron. It is a plant in the genus Thaumatophyllum in the family Araceae. It is a tropical plant usually grown in full sun but can tolerate and adapt to deep shade.

It grows best in rich, moisture-retentive soil that is slightly alkaline. However, it cannot tolerate a high salt concentration in the soil. It is capable of supporting itself at massive heights by producing tree-like bases.

Alternatively, if grown in cooler climates with at least some freezing winter weather, its entire aboveground structures will die completely at a hard frost and sprout back from the roots the following spring.
