They are common biennial plant that grows at such sunny places as at the roadsides, rice fields, and a plain field (biennial plant sprouts in autumn, overwinter, and bear flowers in next spring). They bear Legume (Touka) about 3 to 5 cm long alike peas. The reason for their name is that the peas get matured to turn into black and people compare the black peas as scarecrows. Another name of theirs is ‘Vicia angustifolia var. segetalis’, and the name comes from that the leaves look like a nock (Yahazu: portion receiving a string, behind an arrow). The flower is about 1.5 cm in diameter, tinged with vivid red-purple color. 2 to 3 of the flowers sprout at the root of the leaves, and the flower petals seem to be the wings of butterfly.
