Ailanthus refers to a genus of flowering plants in the family Simaroubaceae. The most well-known species is Ailanthus altissima, commonly known as the tree of heaven. This tree is native to China and is known for its rapid growth and ability to thrive in poor soil conditions. It is often considered an invasive species in various regions outside its native habitat due to its tendency to spread quickly and outcompete native plants. Ailanthus trees have distinctive leaf shapes and are recognized for their strong, unpleasant odor.
