Giant Hogweed ( Heracleum mantagazzianum ) - Invasive species

Giant hogweed, has been spotted for the first time nearby in Virginia.  This invasive plant, which can produce severe burns and blisters, was confirmed in Berryville by the Virginia Cooperative Extension.  

Giant hogweed, which is heavily regulated in Virginia, is one of three plants defined as a Tier 1 noxious weed in the commonwealth.  It can be confused with cow parsnip, which is native to the region West Virginia.

The Jefferson County Health Department has contacted the WV Division of Natural Resources regarding this new development.  Scientists from WVDNR are evaluating the risk of spread to West Virginia and developing a response.  We will keep this site updated as further information comes available.
