Hitchhiking Burdock. The hitchhiking pest, Arctium minus or as it is more commonly known,”burdock.” Did you know it is a wildflower?
It has rounded, spiny structures that many of us call burrs. The burrs attach to clothing and animals so it can spread its seed to other locations.

This hitchhiking burdock is the reason we have VELCRO today. A Swiss inventor in the 1940’s studied the burdocks hook system under the microscope. The burdock had attached themselves to his clothes and his dog’s fur while walking in the woods.
He realized that the same approach could be used to join other things together. The result of his studies was Velcro.
