Conium maculatum L.

A widespread and very toxic invasive species found in wet habitats throughout most of the United States. It is identified in part by the purple spotting on the stems, from which the specific epithet derives. In the eastern United States it is fairly common, in the southwest it grows less frequently along montane streams &c.
