Where Broccoli Comes From | POEM - From ‘You Tell Me’ (Frances Lincoln) Where Broccoli Comes From by Michael Rosen. Not many people know that broccoli grows in the armpits of very big green men who live in the forest and brave broccoli cutters go deep into the forests and they creep up on the very big green men. They wait for the very big green men to fall asleep and the broccoli cutters get out their great big broccoli razors and they shave the armpits of the very big green men. And that’s where broccoli comes from. Not many people know that. Just thought I’d let you know.
