Poisonous hogweed spreads throughout South East

The threat of the giant hogweed - a plant that can blister, burn, and blind - is being taken seriously, say authorities in the south east.

Along riverbanks, like the Medway in Kent, they've been spraying and cutting back the plant, which can reach fifteen feet high.

But despite their efforts, it's spreading elsewhere - and at an alarming rate. And with its spread, comes the warning from plant experts and environmentalists, that the weed is dangerous. And unless efforts to eradicate it are redoubled, more people will be injured.
