Invasive Weed That Causes Blindness And Third-Degree Burns Found in Virginia

Giant Hogweed, a plant whose sap can cause severe burns and blindness, has been found in eastern Virginia. According to the Department of Environmental Conservation, the invasive species from Asia can grow as tall as 14 feet and is topped with an "umbrella" of white flowers. The leaves can grow up to five feet across and the hollow stem, where the sap is stored, has white hairs and purple blotches near the root.

According to Isle of Wight County officials, the sap of the Giant Hogweed is toxic and can cause phytophotodermatitis, a condition where the skin becomes so sensitive that normal sunlight causes third-degree burns. The condition can last for years.
