Giant Hogweed can reach a height of 7 metres (23 ft). A native of Central Asia, it has now spread perniciously along riverbanks in Europe, USA & Canada. The sap of Giant Hogweed causes phytophotodermatitis in humans, resulting in blisters, long-lasting scars and blindness. (5 years and 3124 days ago)
