[Overview]
A perennial that prefers sunny places in lowlands and grows along roadsides around settled areas.
The leaves and flower stalks are usually covered with short hairs.
There is no aboveground stem.
The leaves are basal with long petioles, narrowly spatulate to long lanceolate, 3–6 cm long, with wavy margins and low serrations.
The leaves become wider at fruiting time.
The petioles have almost no wings, which extend only slightly at the top.
The flowers are borne at the tips of upright flower stalks arising from the leaf axils; they are white, about 1.5 cm across, and the petal margins are wavy.
The bases of the lateral petals are usually hairless, and a slender spur 5–7 mm long extends behind the flower.
The summer flowers are cleistogamous.
The fruit is a capsule that splits into 3 when ripe and scatters the seeds.
