Giant Hogweed
The Giant Hogweed plant invades the habitats of native plants and prevents them from growing.
It is harmful to humans and should be avoided wherever possible. If the sap of the plant comes into contact with the skin it can cause severe burns. The skin becomes very sensitive to ultra violet light and the burns can cause painful blistering and swelling.
If you happen to touch a Giant Hogweed you should cover up the affected area and immediately wash with soap and water.
The blisters heal very slowly and can develop into Phytophotodermatitis, a type of dermatitis which flares up in sunlight and for which there is no straightforward treatment.
The species, found most commonly on footpaths, wasteland and along roads and railway lines has a reddish purple stem and spotted leaf stalks.
Giant Hogweed produces thousands of seeds in late summer, which can lie for several years without growing.
Even after the plant dies, its presence can be seen, leaving bare ground, which often causes soil erosion on riverbanks.
It is important that the spread of this plant is left to a minimum and it is controlled sensibly.
If you come across any Giant Hogweed within the highway do not attempt to dispose of it yourself. Note the location and call our Customer Service Centre on 0116 305 0001.
