The University of Illinois Extension is warning local gardeners of toxic plants appearing in gardens.  The more recent concern is poison hemlock, a plant which is common along highways, railroads, and field edges.  However, it can emerge in vegetable gardens and landscaping.  The weed closely resembles other safe plants but can be deadly if ingested.  Andrew Holsinger – a horticulture educator at the University of Illinois Extension – says plants like these are not only dangerous for people but also destructive to good plants. 

Poison hemlock is a biennial plant, which means its life cycle is two years in length.  The varying appearance of this plant over time can make it difficult to spot. 

There are other toxic plants to watch out for, as well, including the castor bean plant.  This makes planning gardening efforts in advance that much more important. 

If you think you have ingested or inhaled poison hemlock, the University of Illinois Extension recommends you call 911 or the Illinois Poison Center Helpline at 1 (800) 222-1222.  More information on invasive species can be found at www.extension.illinois.edu/invasives.
