Common Name: Morning Glory
Morning glory is a small or large, herbaceous perennial plant, usually producing stems around 5 metres long. These stems can scramble over the ground or twine into nearby vegetation for support.
The seeds are sometimes used as an hallucinogen, whilst the plant is commonly grown as an ornamental.
Originating in the tropics of the Americas, but now pantropical.
Scrub and waste places[
]. Moist thickets, sometimes in hedges or waste ground, at elevations of 800 - 1,850 metres[
|Cultivation Status||Ornamental, Wild
Requires a rich well-drained soil in a warm sunny position[
A climbing plant, supporting itself by twining around the branches of other plants[
There are many named forms selected for their ornamental value[
The seed contains small quantities of the hallucinogen LSD[
]. This has been used medicinally in the treatment of various mental disorders.
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.
