About

Ipomoea tricolor, the Mexican morning glory or just morning glory, is a species of flowering plant in the family Convolvulaceae, native to the tropics of the Americas, and widely cultivated and naturalised elsewhere.

How to grow it

In cultivation, the species is very commonly grown misnamed as Ipomoea violacea, which is actually a different, though related, species. I. tricolor does not tolerate temperatures below 5 °C (41 °F), and so in temperate regions is usually grown as an annual. It is in any case a relatively short-lived plant. It prefers a warm, sheltered, sunny position such as a south- or west-facing wall.

Ingesting any part of the plant may cause discomfort.
