[Overview]
A perennial growing on rocky places, gravelly ground and grasslands in the subalpine to alpine zones.
It has a short rhizome.
The leaves consist of basal leaves and 1–2 alternate leaves on the flower stalk; the basal leaves are linear, 3–8 cm long, pointed at the tip, and have fine projections on the margins.
A raceme at the tip of a flower stalk about 6–17 cm tall bears several to about 10 greenish white 6-petaled flowers.
There are 6 stamens, slightly shorter than the tepals, and the anthers are yellow.
The flower stalks are erect.
The fruit is an oblong capsule, longer than the tepals, and is erect, not pointing downward.
The seeds have no tail-like appendages.
[Cultivation]
Propagate from seed or by division.
It prefers well-drained soil, and soil for mountain wildflowers is also fine.
A place with partial shade in summer and sun in other seasons is suitable; avoid strong direct sunlight and afternoon sun in summer, as they can scorch the leaves.
Water thoroughly when the soil surface dries.
In spring and autumn, apply slow-release fertilizer placed on the soil.
There are no particular pests or diseases.
