Swingle has become extensively naturalized in North America since its introduction in 1784. A shade intolerant species resistant to pollution, it is an aggressive pioneer in both natural and urban environments, is characterized by rapid juvenile growth and prolific seed production, and has an incredible ability to coppice once established. Ailanthus populations contain significant genetic diversity but may not be genetically different from native trees. Experience shows that ailanthus is difficult to grow on some sites where fine textured soils or moisture availability may be a barrier to establishment.
