Water hemlock

Cicuta maculata

ToxicLookalikes

The wetland umbel that looks like parsley and kills like a seizure — a teaching plate so fennel, dill, and watercress have a named opposite.

Treat this as a poison-garden specimen. Read Safety before any use.

Water hemlock is a North American wetland Apiaceae. Cicutoxin causes violent seizures. The chambered rootstock is the most toxic part; a bite has killed. Purple-streaked stems and a parsley smell fool foragers who should have stayed home. This plate is identification only. Habitat, not a grow lab you need.

Flavor

Do not taste. A parsley-carrot smell is the trap.
