| Thank you for another interesting question on the "non-native invasive plants of North America forum" (just kidding, actually this is a good forum for wildflower identification questions whether native or invasive). Yes, the Scots "honored" Prince William Augustus, the Duke of Cumberland, whom they call the Butcher of Cumberland for his actions in the Battle of Culloden Moor, 1745, by naming a plant "stinking Willy" after him. The botanical name of this plant is Senecio jacobea. The plant has many common names, the most widely used name is Tansy ragwort. In continental Europe, where it is native, the plant is also called St. James Wort. Senecio jacobea is listed as an invasive weed in Scotland, North America especially the Pacific Northwest, and various other places around the world where it has been introduced. Some people blame the Duke of Cumberland for bringing the plant to Scotland (presumably seeds were carried on the boots of his invading army). Senecio jacobea has flowers similar to sunflowers, deeply cut leaves, smells bad, and is toxic to livestock. Senecio jacobea arrived in the Pacific Northwest about 90 years ago. Three insect species that feed on Senecio jacobea were deliberately released in the Pacific Northwest 40 to 50 years ago, and may be helping to keep it under control.
