Warren County

AMES, Iowa -- Herbs are annuals, biennials and perennials that die back to the ground each year and are used for their flavor, fragrance and medicinal properties.

Control of wild parsnip (Pastinaca sativa) and poison hemlock (Conium maculatum) is the same.  Safely removing these weeds from the landscape is important as both species can be toxic to humans and animals. 

The Warren County Extension Council is one example of this grass roots governing body of the nationwide Cooperative Extension System.
