Ipomoea nil (common name: japanese morning glory)

Propagation: Pre-soak the seed for 12 hours in warm water, or scarify the seed, and sow in individual pots in a greenhouse in early spring. The seed usually germinates in 1 - 3 weeks at 22°c. Plants are extremely resentful of root disturbance, even when they are quite small, and should be potted up almost as soon as they germinate[1]. Grow them on fast in the greenhouse and plant them out into their permanent positions after the last expected frosts. Consider giving them some protection such as a cloche until they are growing away actively.

Cultivation: Requires a fertile well-drained loam in a sunny position[2].

The plant is not frost hardy, but can be grown outdoors as a tender annual in temperate zones[2].

A very ornamental plant, there are several named varieties[2].

Closely related to I. purpurea[3].

Range: Pantropical.

Habitat: Thickets on mountain slopes, waysides, fields and hedges from sea level to 1600 metres in China[4].

Medicinal: The seed is anthelmintic, anticholinergic, antifungal, antispasmodic, antitumour, diuretic and laxative[5][6]. It is used in the treatment of oedema, oliguria, ascariasis and constipation[5]. The seed is also used as a contraceptive in Korea[6].

The seed contains small quantities of the hallucinogen LSD[2][1]. This has been used medicinally in the treatment of various mental disorders.

The pounded plant is used as a hair wash to rid the hair of lice[7].

Soil: Can grow in light, medium, and heavy soils.

Drainage: Prefers well drained soil.

Flower Type: Hermaphrodite

Also Known As: Pharbitis nil
