The Return of the Giant Hogweed

Turn and run!
Nothing can stop them
Around every river and canal their power is growing
Stamp them out!
We must destroy them
They infiltrate each city
With their thick dark warning odour

They are invincible
They seem immune to all our herbicidal battering

Long ago in the Russian hills
A Victorian explorer
Found the regal Hogweed by a marsh
He captured it and brought it home
Botanical creature stirs, seeking revenge
Royal beast did not forget
Soon he came home to London
And made a present of the Hogweed
To the Royal Gardens at Kew

Waste no time!
They are approaching
Hurry now
We must protect ourselves
And find some shelter
Strike by night!
They are defenseless
They all need the sun
To photosensitize their venom

Still they're invincible
Still they're immune
To all our herbicidal battering

Fashionable country gentlemen
Had some cultivated wild gardens
In which they innocently planted
The Giant Hogweed throughout the land
Botanical creature stirs, seeking revenge
Royal beast did not forget
Soon they escaped, spreading their seed
Preparing for an onslaught
Threatening the human race

Mighty Hogweed is avenged
Human bodies soon will know our anger.
Kill them with your Hogweed hairs
