Thistles have evolved an amazing method of protecting itself from plant-eating animals. You can see sharp thorns growing on the base of the flower as well as on the leaves of the plant. I have felt these thorns and they are very sharp!! Of course, there are other types of plants that grow thorns as a form of protection and I am sure you have seen and/or "experienced" them at some time in your lives.
I made these photos in Bay Bulls growing near a cattle farm. To be honest, I don't see thistles in many places around Newfoundland and Labrador!
