Bull Thistle (Cirsium vulgare) also called spear thistle is a plant you don’t want to mess with. It has many sharp spines that can easily penetrate clothing and skin. While the thistle can be a painful to the touch it can be a joy to look at. Its spines leaves and stems, have an interesting architecture, and their purple flowers that appear to come out of a spiky globe are very pretty indeed.
Still, to many it is considered a terrible weed that should be destroyed, and I understand that. Bull Thistle is not native to North America, is a pain to humans in the yard and cattle in the pasture. On many closely cropped pastures you can see Bull Thistles standing tall and unmolested.
If you are brave and well armored pick one of these lovely flowers, and put it in a vase on the kitchen table like my dad once did. It really brightens up a room.
