Native to Eurasia, but introduced to North America and now found throughout the United States and southern Canada.


Annual weeds found commonly in disturbed lots and waste sites. Plants grow profusely and densely to form large mats that cover other foliage. Reproduction is from seeds.


Mature plants may grow as high as 2 or 3 feet due to the dense growth, and cover many square feet of surface area. There is diffuse branching of the thin, weak stems. The leaves are on a petiole and may be over 2 inches long, divided into several leaflets which are themselves deeply lobed or divided. The small flowers occur in dense spikes at the ends of the stems, and are white to pink to violet-white in color.

Characteristicts Important to Control:

No specific recommendations. In non-landscaped areas germination may be prevented with a pre-emergent herbicide, and a non-selective post-emergent is effective in eliminating existing plants.
