Flixweed (also known as tansy mustard) is a vigorous plant and a prolific seed producer. It can be an early spring food source for flea beetles. Plants can germinate in the fall, creating small rosettes that overwinter and begin growing rapidly in the spring. It is important to scout and control early in the season. It is an annual, winter annual or biennial weed that reproduces by seeds.
