Musk Thistle or Nodding Thistle (Carduus nutans L.) identification and control

---

Summary.
The musk thistle or nodding thistle (Carduus nutans L.) is usually a biennial or winter annual, but it occasionally occurs as a summer annual. As a biennial or winter annual, it produces a rosette the first year and develops flowers and seeds the second year. As a summer annual, this thistle completes its life cycle from germination through seed production in the same growing season. Seedlings may emerge anytime during the growing season, but the plants usually remain in the rosette stage for about 90 percent of their life cycle. The rosette, a cluster of tightly packed spreading or radiating basal leaves with little or no stem elongation, may reach 3 to 5 feet in diameter by season's end. Musk thistle plants vary in height from a few inches to over 6 feet depending upon soils and growing conditions. A large plant has a large fleshy taproot that is corky and hollow near the ground surface.
