is a biennial herb originating in Eurasia, found in fields or on
roadsides. The whole is prominently long-haired. Stems branch at
lower parts and spread sideways, the tips becoming somewhat erect.
Cotyledons (seed leaves) at the foot of the stems remain until
flowering time. Most leaves are opposite, 0.7-1cm in length,
0.8-1.2cm in width, in the shape of a long oblong, with 2-4
serrations on margins. Flower stalks, the same length as the leaves,
appear from axils on upper portions and set single light blue-purple
flowers on them. Bloom time: April-May.
