The seeds also contain glycosides, which may cause nausea if consumed. Water them during dry periods, once or twice per week.
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. Even with the plant’s tolerance of poor soil, it actually prefers well-draining soil that is moist, but not soggy. Once plants have reached about six inches or so in height, you may want to provide some type of support for the vine to twine around.
These pesticide coating could be especially dangerous if one has a history of liver disorders and may also cause neural damage. Why are my morning glory plants not flowering?
Sow the seeds of morning glory about ½ inch deep and give them about 8- to 12-inch spacing.  This shift, from red to blue, is induced by chemical modifications affecting the anthocyanin molecules present in the petals. Ideally, the soil should be moist, but not wet. Morning glory species belong to many genera, some of which are: Morning glory was first known in China for its medicinal uses, due to the laxative properties of its seeds. Morning glories prefer full sun but will tolerate very light shade.
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. Commercial seeds are sometimes treated with toxic methylmercury (although the use of methylmercury has been banned in the US and the UK since the 1980s), which serves as a preservative and a cumulative neurotoxic poison that is considered useful by some to discourage recreational use of them.
"The Involvement of Tonoplast Proton Pumps and Na+(K+)/H+ Exchangers in the Change of Petal Color During Flower Opening of Morning Glory, "Synchrony between flower opening and petal-color change from red to blue in morning glory, Ipomoea tricolor cv. , The seeds, vines, flowers, and leaves contain ergoline alkaloids, and have been used for centuries by many Mexican Native American cultures as an entheogen; R. Gordon Wasson has argued that the hallucinogenic seeds used by the Aztecs under the Nahuatl name tlitliltzin, were the seeds of I. tricolor. Sign up to get all the latest gardening tips! I. tricolor does not tolerate temperatures below 5 °C (41 °F), so in temperate regions it is usually grown as an annual.
In some places, such as Australian bushland, some species of morning glories develop thick roots and tend to grow in dense thickets.  According to the book Substances of Abuse, in addition to methylmercury, the seeds are claimed to be sometimes coated with a chemical that cannot be removed with washing that is designed to cause unpleasant physical symptoms such as nausea and abdominal pain. 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 or form of pesticide or methylmercury (although the latter is illegal in the UK and the US). Can morning glory be planted in pots? The main reason of non flowering Morning glory plant is improper nutrient, light and water management. They can quickly spread by way of long, creeping stems. Germination may be improved by pre-soaking in warm water. There are some species which are strictly annual (e.g. Heavenly Blue", https://en.wikipedia.org/w/index.php?title=Ipomoea_tricolor&oldid=987893785, Articles needing additional references from September 2014, All articles needing additional references, Creative Commons Attribution-ShareAlike License, This page was last edited on 9 November 2020, at 21:32. This more widespread knowledge has led to a rise in entheogenic use by people other than Native Americans. Morning glories, both annual and perennial, are typically herbaceous plants with many cultivated varieties being a favorite ornamental for home gardeners. Ipomoea tricolor, the Mexican morning glory or just morning glory, is a species of flowering plant in the family Convolvulaceae, native to the New World tropics, and widely cultivated and naturalised elsewhere. In cultivation, the species is very commonly grown misnamed as Ipomoea violacea, actually a different though related species.
The leaves are spirally arranged, 3–7 cm (1" to 3") long with a 1.5–6 cm (½" to 2") long petiole.
Morning glory (also written as morning-glory) is the common name for over 1,000 species of flowering plants in the family Convolvulaceae, whose current taxonomy and systematics are in flux.   For this reason, Terrence McKenna advocated growing and harvesting your own Heavenly Blue Morning Glory seeds to use for this purpose, and avoid any possibility of pesticide coatings.
 Because it goes by so many names, it can easily be slipped through import inspections, and it is often available in Asian or specialty produce markets. Some cultivars of Ipomoea batatas are grown for their ornamental value, rather than for the edible tuber. In fact, once established they require little attention. The cypress vine is a hybrid, with the cardinal climber as one parent. The genus Ipomoea also contains the sweet potato (Ipomoea batatas). Lysergic acid hydroxyethylamide and ergonovine are also considered to be contributing psychedelic alkaloids in the plant. There is no legal requirement in the United States to disclose to buyers that seeds have been treated with a toxic heavy metal compound. Further research was published in 1960, when Don Thomes MacDougall reported that the seeds of Ipomoea tricolor were used as sacraments by certain Zapotecs, sometimes in conjunction with the seeds of Rivea corymbosa, another species which has a similar chemical composition, with lysergol instead of ergometrine.
