Musk thistle is a biennial or winter annual. Four to six foot tall plants are common.
Deeply lobed leaves are distinguished by a dark green blade with a prominent light green midrib.
Native to southern Europe and western Asia, musk thistle thrives in pastures and range lands, in waste areas, stream banks, and road sides.
Flowers may be violet, purple, or rose colored. Flowers are typically "nodding" or bent over. Ends of stems supporting flowers are often nearly leafless. Bloom is in June and July.
Seed is attached to a soft parachute-like plume.
