Ailanthus altissima commonly known as tree of heaven, ailanthus, or in Chinese as chouchun , is a deciduous tree in the quassia family (Simaroubaceae). It is native to northeast and central China as well as Taiwan. Unlike other members of the genus Ailanthus, it is found in temperate climates rather than the tropics. The tree grows rapidly and is capable of reaching heights of 15 metres (50 ft) in 25 years. However, the species is also short lived and rarely lives more than 50 years.A. altissima was first brought from China to Europe in the 1740s and to the United States in 1784. It was one of the first trees brought west during a time when chinoiserie was dominating European arts, and was initially hailed as a beautiful garden specimen. However, enthusiasm soon waned after gardeners became familiar with its suckering habits and its offensive odour. Despite this, it was used extensively as a street tree during much of the 19th century. Outside of Europe and the United States, the plant has been spread to many other areas beyond its native range.
