Pathway of Introduction and Spread
Native to Europe, produces thousands of viable seeds per square meter, and readily regenerates from root fragments. Dispersed unintentionally by people, both through human activity and trade (along railroad tracks). Plant can break off and be dispersed by wind along with their seeds. Will also produce new stems up to one meter away from parent stems.
Forms dense populations, alters plant community composition and structure when it invades
perennial grasslands . Has potential to form monotypic stands—has become severe problem in South Dakota.
