Cultivation Details

Ipomoea alba is a plant mainly of tropical climes, also growing in subtropical areas and cultivated as an annual in temperate regions. It is not very cold-hardy, tolerating occasional temperatures down to between -5 and -10°c[]. Another report says that plants need a minimum temperature of 5°c if they are to overwinter successfully[].
Requires a fertile well-drained loam in a warm sunny position[].
A fast-growing climbing plant, it is best grown as a temporary screen in the garden or along the boundary edge[]. Plants need a long period of growth to reach flowering size and so are not very suitable for growing in pots in a greenhouse[].
The plant forms tubercles (baby tubers) on the stems and can be propagated by them[].
The aromatic flowers open of a night time[].

Edible Uses

Other Uses

The milky juice (sap?) is used to coagulate the latex of Castilla elastica[].

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[]. Grow them on in the greenhouse for at least their first winter then plant them out into their permanent positions in late spring or early summer, after the last expected frosts.
Cuttings of side shoots in a peaty soil.
Layering.
Plants form tubercles on their stems[]. These can be stored overwinter in a slightly moist medium such as sand or leafmould, keeping them in a cool but frost-free place. Pot them up in early spring.
