Safety note: Extremely toxic — considered the most violently poisonous plant in North America. Roots can cause fatal seizures; do not handle.

Spotted Water Hemlock is a tall wetland plant in the carrot family with purple-mottled hollow stems and compound white flower clusters. The roots and stems contain cicutoxin, a potent neurotoxin that can kill a human or large animal within hours of ingestion. The flowers superficially resemble elderberry and Queen Anne's lace, making misidentification dangerous.
