Common Mullein was introduced by European settlers in the mid-1700s for use as a fish poison (leaves contain rotenone) and as a medicine. The main threat posed by Mullein is to natural meadows and forest openings where it colonizes very quickly. Mullein is extremely adaptable and out-competes native herbs and shrubs allowing the plant to monopolize an area very quickly. Each plant produces hundreds of seeds which can survive dormant for decades. Once colonized, it can be extremely difficult to eradicate.
