Source? likely to be reintroduced: 

The risk of introduction of Melilotus officinalis is very high. As a plant often considered useful, it has been intentionally introduced to many temperate and tropical regions and has recurrently escaped from cultivation. It is also a prolific seeder, with seeds that remain viable for many years, and well adapted to a wide range of habitats. Therefore, even when its use in agriculture has declined in recent years, the likelihood of it colonizing new areas still remains high.
