Originally introduced in to Britain as an ornamental plant in the 19th century, giant hogweed is particularly toxic and its sap can cause severe burns, blistering and even blindness.

Efforts to control its spread have proven futile and now, despite concerted efforts to stop it, recent reports from the Massey Herbarium at Virginia Tech university have revealed that it has started to turn up in Clarke County as well - making Virginia the eighth US state to have been affected.Locals have been warned to keep away from it and report any sightings.

The plants are particularly difficult to eradicate because their seeds can remain viable for years.
