This plant was the wild thistle that grew in patches. This allowed the Scots to escape. It is for this reason that the wild thistle is named the national flower of Scotland.
Once an invading Viking army attempted to sneak up at night while the Scottish army was sleeping. When one barefooted Viking stepped upon a thistle and let out a loud cry the Scottish army was alerted.
The thistle is the symbol of the Order of theThistle. This is a high chivalric order of Scotland. It is also a Celtic symbol of nobility of charaacter and of noble birth. It is used as a symbol in other areas of Scottish life.
Pleny the Elder taught that the thistle could grow hair on bald heads.
More recently it has been used for plague, headaches, canker sores, toothache, and vertigo. This sounds like the old snake oil sold in the wild west by traveling salesmen.
The beautiful yellow and black Gold finches love thistle seeds.
The thistle leaves are good for the health of home rabbits.
Thistle plants contain vitamins A, B, C, calcium, and are high in fiber.
Pliny the Elder, a Roman naturalist among many significant disciplines, believed that thistles could cure baldness. However, he did not say what to do with them.Roman Emperor Tiberius only had his hair cut during a full moon otherwise he would become bald. We may suppose that, since one planting by the signs can plant nothing during a full moon, a hair cut would be in order.
