Poison Hemlock
Poison hemlock is a highly poisonous biennial herbaceous flowering plant in the carrot family Apiaceae, native to Europe and North Africa.
All parts of the plant are toxic, especially the seeds and roots, and especially when ingested.
The plant is often found in poorly drained soil, particularly near streams, ditches, and other watery surfaces. It also appears on roadsides, edges of cultivated fields, and waste areas.
