The term "pepper tree" commonly refers to the Schinus molle, also known as the Peruvian pepper tree. This tree is native to South America and is characterized by its long, drooping branches and feathery leaves. It produces small, pink berries that resemble black peppercorns but are not true pepper. The tree is often used for ornamental purposes in landscaping due to its attractive appearance. Another type of pepper tree is the Schinus terebinthifolius, or Brazilian pepper tree. This species is also known for its bright red berries and is often found in warmer climates. Both types of pepper trees can be invasive in certain regions, outcompeting native plants and altering local ecosystems.
