Warning : Giant Hogweed - Avoid this Plant !
"The Giant Hogweed is an invasive plant whose sap causes third-degree burns and blindness. It can reach heights of 14 feet and is found throughout North America. This year, officials are particularly alarmed by an increase of sightings of this massive flesh-eater in New York State.
The Giant Hogweed has white flowers with 50-150 flower rays clustered into an umbrella shape that are up to 2.5 feet across. It can grow between 7 and 14 feet tall. It has large, incised leaves that can grow up to 5 feet across. The stems are green with extensive purple splotches and coarse white hairs. They are hollow, ridged and 2-4 inches in diameter.
The burns from the sap of a Giant Hogweed appear as painful blisters within 48 hours of contact. Scars can last up to 6 years, although typically don't last more than a month. The sap can cause blindness if it makes contact with the eyes."
