Water hemlock is considered to be North America’s most poisonous plant as it is incredibly poisonous to humans. The plants contain a toxin named cicutoxin which causes seizures.

This poison is found in all parts of the plant but is most concentrated in the roots, which is most potent in the spring. The plants all have very distinctive small white or green flowers, arranged in an umbrella shape.
