Weed spotlight: Poison hemlock

Tina Booton

Look out for the kids and livestock. Poison hemlock is all over the river bottom and spread from this area with the flood waters from 2013. All parts of this plant are poisonous. This is the plant that killed Socrates. Poison hemlock has carrot-like top growth and purple spots on the hollow stems. The plants can reach up to 10 feet tall. The white flowers on the top resemble Queen Ann's lace. The picture shows the seed formation of this plant. This biennial plant on the C list can be pulled or sprayed with chemicals.
