Sulfur plays an important role in plant physiological processes functioning as one of the macro‐elements, but high soil sulfur is toxic to most of the plants. Exotic Spartina alterniflora , a blacklist invasive species in China, actively accumulates and stores sulfur in their tissues leading to high sulfide concentration in the invaded environment. Spartina alterniflora might be using high sulfur as a chemical tool in successful competition with indigenous species as e.g., Phragmites australis . As the supply of sulfur increases due to acid rain and rising sea levels, plant invasions will likely become more problematic around the world.
