Answer 2

Tree-of-heaven -- or Ailanthus -- is an invasive triple threat, according to a team of plant pathologists. The species produces seeds early in its lifespan, tends to make millions of viable seeds during its life, and continues to produce seeds for decades and, in some cases, for more than a century.
