[Overview]
A perennial with a corm.
The corm is small, round to egg-shaped, and covered with an outer coat.
The stem is slender and erect.
The leaves grow from the base in a fan shape and are linear to sword-shaped.
It grows from autumn to spring, and the above-ground parts die back in summer as the plant goes dormant.
A spike at the stem tip bears many 6-petaled flowers.
The floral tube ranges from short and funnel-shaped to long and tubular, widening toward the tip.
The tip of the stigma is shortly 3-lobed.
The fruit is an oblong capsule.
[Cultivation]
Propagate by dividing the corms.
In areas without frost it can overwinter outdoors, and when planted in the ground it grows well left in place for several years.
In areas with frost, if the bulbs are planted early in autumn, protect them from frost, for example by moving them into a frame, so that the emerging leaves are not damaged.
It prefers fertile soil that is sunny and well drained.
Take care not to overwater; for potted plants, water when the soil surface dries during the growing period, and stop watering during dormancy.
For plants in the ground, rainfall is sufficient.
Apply liquid fertilizer once a month during the growing period.
There are no particular pests or diseases.
