habit
Along railroads and roadsides; in dry fields and on river banks; shores (even among driftwood on Lake Superior); refuse heaps and other disturbed places. Presumably native to western North America, but long cultivated and early introduced to Europe. First collected in 1891 in Washtenaw Co.
Well known as a garden ornamental and also as a crop plant for the oil from its seeds, which are also popular in themselves as nutritious food for humans, birds, and other creatures. Hence, the species frequently escapes from cultivation as a weed. Such escapes are frequently depauperate.
