Philodendron is a large genus of flowering plants in the family Araceae.

Regardless of number of species, the genus is the second-largest member of the family Araceae. Many are grown as ornamental and indoor plants. The name derives from the Greek words philo- or "love, affection" and dendron or "tree". The generic name, Philodendron, is often used as the Engish name, "philodendron"
