The plant is thought to have arrived in the United States when American farmers, looking for inexpensive flax seed in the 1870s, bought contaminated seeds from Russia and inadvertently planted the thistle, which responded well to the dry, windy conditions of the West, said Jeffrey Dukes, a professor of forestry and natural resources at Purdue University.The plant is thought to have arrived in the United States when American farmers, looking for inexpensive flax seed in the 1870s, bought contaminated seeds from Russia and inadvertently planted the thistle, which responded well to the dry, windy conditions of the West, said Jeffrey Dukes, a professor of forestry and natural resources at Purdue University.

In Washington, Mr. Thorson said the problem began after the tumbleweeds rolled down the 40-foot berms along the highway and onto the road.
