About

Musk thistle is a tall biennial with large, drooping, deep-pink to purple flowerheads and spiny, waxy-green leaves that fold into a distinctive nodding head as the plant matures. A single plant can produce over 10,000 seeds, making it one of the most aggressive invasive thistles across North American rangeland.
