The philodendron (philodendron quinquenervium) is a large genus of flowering plants in the family Araceae and is native to North, Central, and South America. Many are grown as ornamental and/or indoor plants. The name derives from the Greek words philo-, "love, affection," and dendron, which means "tree". They are commonly called by their generic name.
Description[]
The leaves are usually large and imposing, often lobed or deeply cut, and may be more or less pinnate. They can also be oval, spear-shaped, or in many other possible shape variations.

The leaves are borne alternately on the stem. A quality of philodendrons is that they do not have a single type of leaf on the same plant. Instead, they have juvenile leaves and adult leaves, which can be drastically different from one another.
