Control Poison Hemlock Now!

This non-native invasive weed is among the most deadly plants in North America.  This biennial weed spends its first year as a basal rosette and the second year as an erect, towering flowering plant that can measure 6-10' tall.  Despite its common name, poison hemlock is not a tree; it is a member of the carrot family, Apiaceae (formerly Umbelliferae).
