|discussion=<p><i>Barbarea vulgaris</i>, which is sometimes grown as a potherb, is highly variable in length and orientation of fruit and fruiting pedicel, style length, and the division of cauline leaves. Several varieties have been recognized, and they represent some of the many points along one continuum. In my opinion, it is better not to recognize any infraspecific taxa in North America.</p>
