Invasive plant Solidago canadensis is more competitive in its introduced range due to increased production of allelopathic compounds. A study compared plants from the USA and China, finding higher levels of allelochemicals in Chinese samples. These compounds inhibited the growth of native plants more effectively, contributing to S. canadensis' competitive advantage in its new environment.
