A cultivar of Matthiola incana (L.) R.Br. See Matthiola incana 'Dwarf Stock' for a brief description of the type.  ‘The German growers have a formidable list of kinds [of Ten-week Stock], many of which are more curious than showy.  There are, however, sufficient good colours among them, such as crimson, rose, purple, violet, and white, to yield distinct hues.’  [Robinson - The English Flower Garden and Home Grounds 10th Edition, p.680/1907].
