Ipomoea purpurea, the common morning-glory,[2] tall morning-glory,[3] or purple morning glory, is a species in the genus Ipomoea, native to Mexico[4] and Central America.

Description

Like all morning glories, the plant entwines itself around structures, growing to a height of 2–3 m (6 ft 7 in – 9 ft 10 in) tall. The leaves are heart-shaped and the stems are covered with brown hairs. The flowers are trumpet-shaped, predominantly blue to purple or white, and 3–6 cm (1.2–2.4 in) in diameter.[5]

Distribution and habitat

The plant is predisposed to moist and rich soil, but can be found growing in a wide array of soil types.[6] It is naturalized throughout warm temperate and subtropical regions of the world. Although it is often considered a noxious weed, I. purpurea is also grown for its attractive purple and white flowers, and has many cultivars. Common cultivars include I. purpurea 'Crimson Rambler' (red-violet blossoms with white throats), 'Grandpa Ott's', 'Kniola's Black Knight', 'Star of Yelta' (blossoms in varying shades of deep purple with white or pale pink throats), and 'Milky Way' (white corolla with mauve accents).

Chemistry

The triangular seeds have some history of use as a psychedelic; they, like I. tricolor, may contain LSA.[6] Effects are reported to be somewhat similar to those of LSD.[7]

Flower color

Acylated cyanidin glycosides can be isolated from violet-blue flowers of I. purpurea. These anthocyanins were all based on cyanidin 3-sophoroside-5-glucoside, acylated with caffeic acid and/or p-coumaric acid.[8]

Acylated pelargonidin glycosides can be isolated from the red-purple flowers of I. purpurea. The acylated anthocyanins were all based on pelargonidin 3-sophoroside-5-glucoside, acylated with caffeic acid and/or glucosylcaffeic acid.[9]

Toxic treatments

Commercial morning glory seeds are commonly treated with toxic

which?] that cannot be removed with washing that is designed to cause unpleasant physical symptoms, such as nausea and abdominal pain. The book states that this chemical is also toxic.[11]
