The Oversized Invasive Carrot That Can Give You Third Degree Burns

Giant hogweed is a dangerous, invasive plant originally from the Caucasus Mountains. It can grow over 4 meters tall and cause severe skin burns due to its sap containing furanocoumarins. Introduced to Europe and the US for ornamental purposes, it has spread widely, especially in New York. Its invasiveness is due to its rapid growth and seed production, which outcompetes native species. The plant's sap can cause phytophotodermatitis, leading to long-lasting skin damage.
