The tree of heaven is a tall tree with big, green leaves that can grow very quickly! It has a strong smell that some people say is like burnt peanuts.

Habitat: Urban areas

Appearance

The tree-of-heaven is a rapidly growing deciduous tree, often recognized by its long, compound leaves featuring 10-40 leaflets, each with a distinctive tooth and gland near the base. Its smooth, pale grey bark on young trees darkens and fissures with age, while its clusters of papery, reddish-brown winged seeds, called samaras, persist into winter.
