Carduus nutans (musk thistle) is a biennial or winter annual (family Asteraceae) found in disturbed open sites, roadsides, pastures, annual grasslands, and waste areas, but is mostly limited to the Klamath and Cascade Ranges, northern Sierra Nevada, and Modoc Plateau in California. Previous populations in southern California were eradicated.

Cal-IPC Inventory rating: Moderate
