Virginia Tech Scientists who Identified Dangerous Giant Hogweed in Clarke County Hopeful That it will be Contained (Jun 18, 2018)

Virginia Tech.

Virginia Tech researchers who helped identify the dangerous Giant Hogweed plants in Clarke County, Virginia, want residents to stay on the lookout for the plant with toxic sap that can cause severe burns — but also stressed that the weeds are believed to have been planted intentionally decades ago and haven’t spread in the years since. Anyone who suspects they have found Giant Hogweed should take photos, check online to compare the plant to giant hogweed photos, and then contact a Virginia Cooperative Extension agent.
