Hemerocallis fulva var. disticha ("Nokanzo")
Japanese name: ノカンゾウ (野萱草)
Scientific name: Hemerocallis fulva var. disticha
[Overview]
A perennial 50–70 cm tall, growing on river banks and in fields.
It has long creeping rhizomes, and the roots sometimes have spindle-shaped swellings.
The leaves arise from the base in two rows.
The leaves are simple and linear, 50–70 cm long and 1–1.5 cm wide.
A dichasial cyme is produced at the tip of a flower stalk 50–70 cm tall, and about 10 orange-red, six-petaled flowers are borne facing upward at the end of each branch.
The upper part of the flower stalk has small bracts.
The tepals are 7–8 cm long, with the tips slightly recurved.
The flowers open in the early morning and wither in the evening, lasting only one day.
The stamens are shorter than the tepals.
The fruit is a capsule, but it rarely sets fruit.
[Uses]
The buds, roots and leaves are used medicinally.
The young shoots, young leaves and flowers can be eaten.
[Cultivation]
Propagate by division.
It prefers a sunny, well-drained site rich in organic matter.
It is hardy, and when planted in a garden it grows well even if left alone.
Water thoroughly when the soil surface dries.
In addition to a base fertilizer, apply slow-release fertilizer once each in March–April and September–October.
Once the flowers are finished, remove the spent flowers promptly.
When the underground stems become crowded, the plant declines from the center of the clump, so in that case divide it.
Aphids can occur.
