Ever wondered where Velcro came from?
Look no further; the chap who invented Velcro got the inspiration from burdock burrs. They're the weirdest things; even when the burrs are still green before the flower has opened, hooks on each of these spikes will stick the burr to anything - dogs' coats, your clothing, even your skin. They're not sharp, just sticky.
Burdock, or Arctium lappa, has many medicinal uses but related species Arctium minus is a pest plant in some areas, particularly on sheep farms as burrs and wool together are bad news.
