Musk thistle is found throughout the U.S. except for Maine, Vermont, Florida, Alaska and Hawaii. A silver gray leaf margin is characteristic of each spine tipped lobe. Root architecture of prairie grasslands, which depends on plant phenology and edaphic conditions, strongly influences susceptibility to invasion by nonindigenous plant species. Because musk thistle is a biennial or winter annual species, there is a rosette stage of the plant prior to it bolting during the next growing season. 1988). Musk thistle may germinate and grow under a wide range of environmental conditions, infesting arid areas in Nevada and relatively high moisture areas of Virginia and the east coast. Musk and plumeless thistles hybridize and are very similar in the rosette stage.
