After the iris has flowered, it produces a seed capsule between June and August. [2]

Biochemistry

It is written as 水仙花鸢尾 in Chinese script, [2] and known as shui xian hua yuan wei in Pidgin. [2] [8]

The Latin specific epithet narcissiflora refers to having narcissus-like flowers. [9]

They can be found at an altitude of 3,900 m (12,800 ft) above sea level. [6]

Cultivation

It is hardy, [4] to RHS Zone H7. [6] Meaning colder than −20 °C (or < -4 °F). [13]

It prefers to grow in well-drained soils, in sun or partial shade. [4]

It takes time for the plant get established in new planting sites. [3]

It is a rare plant in Europe. [3] [4]

In some herbariums and Botanical Gardens, specimens labelled as Iris narcissiflora have later been re-classified as Iris dolichosiphon . [3]
