Douglas' Water Hemlock

Cicuta douglasii (de

Overview

Douglas' Water Hemlock (Cicuta douglasii) is a toxic annual or biennial plant in the Apiaceae family. Native to western North America, it is also found in wet lowlands such as seeps, meadows, or riparian areas. It grows quickly, with hollow, ridged stems that can reach heights of nearly 10 feet. Its small white flowers are both male and female and bloom in flat umbels in late summer. Its bulbous base contains a highly toxic volatile oil and should not be eaten or touched. Its seeds can survive in the soil for many years and must be eliminated to eliminate the infestation. Douglas' Water Hemlock must be systematically managed, as it can be a threat to both human health and wildlife.
