The plant establishes easily and in high abundance in human impacted and disturbed areas, invading roadsides, wastelands and poor or overgrazed pastures. It is considered an invasive species in Europe, parts of Asia and Australia, although it is not an extremely competitively aggressive species and is mainly considered a noxious weed that interferes with other cultivated crops. The main impact of this plant is the copious amount of pollen produced from male flowers that are allergens to sensitive people, compounding health problems like rhinitis, oculorhinitis, asthma and causing skin irritations[

Propagation

Seed - in nature the seed ripens in the autumn and then enters a dormancy period that requires a cold stratification in order to germinate. Germination occurs in the spring with only a portion of the seed bank germinating while the rest of the seeds enter a secondary dormancy period. The secondary dormancy of the seed makes this species well adapted at surviving in continuously disturbed sites. Seeds have been known to remain viable after 20 years of burial with 85% germination rate[
