Quick Summary
Tumble mustard, also known as tumbling mustard, is a tall, European biennial herb (Sisymbrium altissimum) that has become a troublesome weed in North America. It is characterized by its pinnatifid leaves and long, slender seed pods.1
As a type of tumbleweed, tumble mustard breaks away from its roots and is carried by the wind, scattering its seeds as it rolls. This characteristic makes it a widespread weed, similar to other tumbleweeds like pigweed and Russian thistle.2
