A native of Europe, now found throughout the United States.
An annual reproducing only from seeds. It can be a problem in all situations, including landscape, crops, and roadsides or ditchbanks.
The entire plant has a very strong, almost skunk-like odor.
Mature plants have many stems arising from the base, and may grow to 16 inches in height or may stay more prostrate and stay around only 2 inches in height. Stems begin prostrate but usually begin to bend upward at their ends to grow more ascending.
Leaves are only about 1 inch long and are divided into narrow, toothed segments, giving them a feather-look. Lower leaves may be on short stalks while upper leaves are without stalks.
Flowers are tiny, greenish to yellowish-white, and occur at intervals along the flower stems. As the seeds mature the flower falls, and the seed pod develops to about 1.5 inches in length and deeply wrinkled.
