| Remarks : | This plant is introduced to the U.S. where it is considered a noxious weed. Known as Canada thistle in the U.S. Canada thistle was introduced to the United States, probably by accident, in the early 1600s and, by 1954, had been declared a noxious weed in forty three states. In Canada and the U.S., it is considered one of the most tenacious and economically important agricultural weeds, but only in recent years has it been recognized as a problem in natural areas. |
