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 odorThey are invincible
They seem immune to all our herbicidal batteringLong ago in the Russian hills
A Victorian explorer found
The regal Hogweed by a marsh
He captured it and brought it homeBotanical creature stirs, seeking revenge
Royal beast did not forget
He came home to London and made a present of the Hogweed
To the Royal Gardens at KewWaste 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 photo sensitize their venomStill they're invincible
Still they're immune to all our herbicidal batteringFashionable country gentlemen had some cultivated wild gardens
In which they innocently planted the giant Hogweed throughout the landBotanical creature stirs, seeking revenge
Royal beast did not forget
Soon they escaped, spreading their seed preparing for an onslaught
Threatening the human raceMighty Hogweed is avenged
Human bodies soon will know, anger
Kill them with your Hogweed hairs
