Japanese name: ミヤマスミレ（深山菫） Scientific name:Viola selkirkii
[Overview]
A perennial 3–10 cm tall, found in moist places in summer-green forests from the mountains to the subalpine zone.
It has a short underground stem.
After flowering, it often sends runners underground and reproduces by forming young plants along them.
The leaves are broadly ovate to ovate-round, 2–4 cm long, with a deeply heart-shaped base.
Both sides of the leaves are often covered with short hairs.
The underside of the leaf is sometimes tinged with purple.
The leaf margins have coarse wavy teeth.
The petioles are 3–10 cm long and sometimes tinged with purple.
The flowers are borne at the tips of flower stalks 5–8 cm long; they are 1.5–2 cm across and reddish purple, with the center of the lip petal white with purple streaks.
The bases of the lateral petals are hairless.
A thick spur 0.6–0.8 cm long extends behind the flower.
The fruit is a capsule that splits into 3 when ripe and scatters the seeds.
