|discussion=<p><i>Spergula arvensis</i> is often a significant weed in sandy crop lands, but it is sometimes used as a forage crop in areas with poor, sandy soils; it was intentionally introduced to Crawford County, Michigan, in 1888 (O. Clute and O. Palmer 1893). Historical collections are known also from Kansas, Nebraska, North Dakota, and South Dakota, where <i>Spergula arvensis</i> may have been introduced but apparently did not persist.</p>
