Petioles are 2 to 17 cm. The white to lilac flowers are 10 to 13 mm long. Peduncles are about the same length as petioles. The lower three petals have purple lines. The lateral pair are lightly bearded.
It is used as the foodplant for the pearl-bordered fritillary and the small pearl-bordered fritillary. It is a known host for the pathogenic fungi Hendersonia violae and Puccinia fergussonii.[4]
