A native of Eurasia, widespread as a weed. The earliest Michigan specimen seen is from Berrien Co. in 1896, but collections were made in Kent and St. Clair Cos. the following year, and the species is now found throughout on sandy or gravelly roadsides, shores, fields, railroads, gravel pits; spreading into forests.
This is an easily recognized species, with its pinnatisect leaves (the upper ones often resembling a Myriophyllum leaf) and elongate linear siliques on thick pedicels, so that the fruit and pedicel appear to be one at first glance. The petals are a paler yellow than the bright ones of our other species.
