What is giant hogweed?
Giant hogweed is an invasive plant known for its enormous size.
- It can grow from 8 – 14 feet high (2.5 – 4 m).
- The leaves of the plant can grow to 3 feet (1 m) in width and have hairs on the underside.
- The plant has hollow stems with dark reddish-purple splotches and coarse white hair.
- The plant produces flattened oval shaped fruit and in the summer, small white flowers form.
Is giant hogweed a risk to human health?
Yes
, a clear watery sap is found in the stem and hairs of giant hogweed.
Contact with sap can cause a skin reaction where skin becomes sensitive to the ultraviolet light in sunlight.
Reactions will depend on the sensitivity of the individual and can lead to painful:
-
- Burns
- Temporary/permanent blindness if sap comes into contact with eyes.
- Blisters - can lead to purple and black scars that may last for long periods
Heat and moisture (sweat) can enhance the skin reaction.
Reactions can occur up to 48 hours after contact.
No Giant Hogweed was seen when this cache was placed. However it was placed in the winter.
Good Luck and Happy Caching!
