Tree-of-heaven's prolific seed production adds to its invasive potential | Penn State University
Ailanthus, also called tree-of-heaven, is a voracious invasive plant species that is rapidly affecting more and more forests in the United States, according to plant pathologists. These researchers recently found that Ailanthus not only produces lots of viable seeds, but also that the species produces seeds earlier in its lifespan and keeps producing seeds, in some cases, more than a century later. Recognizing the invasive potential of Ailanthus may help forestry experts control it.
