Giant Hogweed – Please Be Careful!

Giant Hogweed is found in Cornwall.  Hogweed looks like the innocuous cow parsley with white flowers clustered in an umbrella-shaped head that is up to 80cm in diameter.

Look for a thick green stem spotted with dark red which varies from three to eight-centimetres thick.  Each dark red spot on the stem surrounds a hair, and large, coarse white hairs occur at the base of the leaf stalk. It can grow up to five metres tall and its sap contains toxic chemicals which react with light when in contact with human skin, causing blistering within 48 hours.

What to do if you get its sap on your skin

Wash the area immediately with soap and water. If you feel unwell or have a severe reaction you are advised to see a doctor.
