Morning glory (also written as morning-glory [1] ) is the common name for over 1,000 species of flowering plants in the family Convolvulaceae, whose current taxonomy and systematics are in flux. Morning glory species belong to many genera, some of which are:

As the name suggests, most morning glory flowers unfurl into full bloom in the early morning. The flowers usually start to fade a few hours before the corolla begins to display visible curling. They prefer full solar exposure throughout the day, and mesic soils. Some morning glories, such as Ipomoea muricata , Ipomoea alba , and Ipomoea macrorhiza , are night-blooming flowers.

History

Ipomoea nil , a species of morning glory, was first known in China for its medicinal uses, due to the laxative properties of its seeds.

Ancient Mesoamerican civilizations used the morning glory species Ipomoea alba to convert the latex from the Castilla elastica tree and also the guayule plant to produce bouncing rubber balls. [2] The sulfur in the morning glory's juice served to vulcanize the rubber, a process antedating Charles Goodyear's discovery by at least 3,000 years. [3] Aztec priests in Mexico were also known to use the plant's hallucinogenic properties (see Rivea corymbosa ).

Invasive species

In some places, such as Australian bushland, some species of morning glories develop thick roots and tend to grow in dense thickets. They can quickly spread by way of long, creeping stems. By crowding out, blanketing, and smothering other plants, morning glory has turned into a serious invasive weed problem. [4]

In parts of the US, species such as Calystegia sepium (hedge bindweed), Ipomoea purpurea (common morning glory) and Ipomoea indica (blue morning glory) have shown to be invasive. In fact, as of 2021, most non-native species of Ipomoea are currently illegal to cultivate, possess, and sell in the U.S. state of Arizona, and before 4 January 2020, this ban applied to native species, too. This is because some species of Convolvulaceae (like Convolvulus arvensis and Ipomoea × leucantha ) have been known to cause problems in crops, especially in cotton fields. [5] [6] Ipomoea aquatica is a federal noxious weed, though some states, like Texas, have acknowledged its status as a vegetable and allow it to be grown. [7] [8]

Cultivation

In cultivation, most are treated as perennial plants in frost-free areas and as annual plants in colder climates, but some species tolerate winter cold. Some species are strictly annual (e.g. Ipomoea nil), producing many seeds, and some perennial species (e.g. I. indica ) are propagated by cuttings. Some moonflowers, which flower at night, are also in the morning glory family.

Because of their fast growth, twining habit, attractive flowers, and tolerance for poor, dry soils, some morning glories are excellent vines for creating summer shade on building walls when trellised, thus keeping the building cooler and reducing heating and cooling costs.

Popular varieties in contemporary western cultivation include 'Sunspots', 'Heavenly Blue', moonflower, cypress vine, and cardinal climber. The cypress vine is a hybrid, with the cardinal climber as one parent.

Many morning glories self-seed in the garden. They have a hard seed coat, which delays germination until late spring. Germination may be improved by soaking in warm water. [9]

Morning glory has been a favorite flower in Japan for many a long century. [10] The cultivation started in the Nara period (8th century). [10] The big booms of the selective breeding of the morning glory happened in the Edo era (17-19th century). [10] The large-flowered morning glory was broadly cultivated as a hobby flower. The varied Japanese morning glory (変化朝顔 Henka-asagao or mutant morning glory) was created. [10] [11]

Ipomoea aquatica , known as water spinach, water morning glory, water convolvulus, ong-choy, kang-kung, or swamp cabbage, is popularly used as a green vegetable, especially in East and Southeast Asian cuisines. In the US, I. aquatica is a federal noxious weed, and can be illegal to grow, import, possess, or sell without a permit. A market exists, though, for the plant's powerful culinary potential. [8] As of 2005, the state of Texas has acknowledged that water spinach is a highly prized vegetable in many cultures, and has allowed it to be grown for personal consumption, in part because it is known to have been grown in Texas for more than 15 years and has not yet escaped cultivation. [7]

The genus Ipomoea also contains the sweet potato (I. batatas). Though the term "morning glory" is not usually extended to I. batatas, sometimes it may be referred to as a "tuberous morning glory" in a horticultural context. Some cultivars of I. batatas are grown for their ornamental value, rather than for the edible tuber.

Chemistry and ethnobotany

The seeds of many species of morning glory contain ergoline alkaloids such as the psychedelic ergonovine and ergine (LSA). Seeds of Ipomoea tricolor and Turbina corymbosa (syn. R. corymbosa) are used as psychedelics. [12] The seeds of morning glory can produce a similar effect to LSD when taken in large doses, often numbering into the hundreds. Though the chemical LSA is not legal in some countries, the seeds are found in many gardening stores; however, some claim the seeds from commercial sources can sometimes be coated in some kind of pesticide or methylmercury (although the latter is illegal in the UK and the US).

Convolvulaceae, commonly called the bindweeds or morning glories, is a family of about 60 genera and more than 1,650 species.

<span class="mw-page-title-main">Lysergic acid hydroxyethylamide</span> Chemical compound

D-Lysergic acid α-hydroxyethylamide, also known as D-lysergic acid methyl carbinolamide, is a Lysergamide and alkaloid of the Ergoline family, it is present in higher concentrations in the parasitic fungi species "Claviceps", mainly the Claviceps paspali, also in Claviceps Purpurea. This fungi grows in various species in the Convolvulaceae family like the Ipomoea violacea, the Rivea corymbosa (Ololiuhqui), and the Argyreia nervosa. Heavenly Blue Morning Glory and Hawaiian Baby Woodrose especially contain high amounts of LSH, with content varying between species and by how fresh the seeds are. LSH is a psychoactive Ergoline and has effects similar to LSD due to similarity in the structure and is the main psychoactive compound found in Claviceps Paspali and in (fresh) Heavenly Blue Morning Glory Seeds. LSH is unstable and breaks down into LSA quickly, so old seeds often only contains LSA and iso-LSA. When the seeds are fresh, they contain significantly higher amounts of LSH.

The species is native to tropical parts of the Americas, and has more recently been introduced to North America. It now occurs there from Arizona to Florida and north to Ontario and North Dakota. Like most members of the family, it is a climbing vine with alternate leaves on twining stems. The flowers are blue to rose-purple with a white inner throat and emerge in summer and continue until late fall. The leaves are typically three-lobed, but sometimes may be five-lobed or entire. Flowers occur in clusters of one to three and are 2.5–4.5 cm long and wide. The sepals taper to long, recurved tips and measure 12–24 mm long.

<i>Ipomoea heptaphylla</i> Species of flowering plant

Ipomoea heptaphylla, sometimes known as Wright's morning glory in the United States, is a species of morning glory. It is incorrectly classified as I. wrightii in American publications, but is incorrectly known as I. tenuipes in Africa and India. It is an annual or short-lived perennial vine which climbs using twining stems, and has pink or purple flowers. The leaf shape is somewhat variable, with individuals possessing compound leaves palmately divided into five leaflets, and lanceolate-leaved individuals occurring in neighbouring populations. The name heptaphylla actually means 'seven-leaved'. This plant has a very extensive distribution, from Texas and adjacent states in the southeastern USA to Misiones in northern Argentina, the Greater Antilles of the Caribbean, India, Sri Lanka and East and Southern Africa. Despite its wide distribution it is uncommon throughout its range. The rediscovery of the presence of the species in India after an absence of over half a century was published in 2014. The species appears to favour dry subtropical to tropical habitats.
