Morning Glories, Sweet Potato Ipomoea violacea.jpg Ipomoea Convolvulaceae Some species are very weedy The genus Ipomoea, with over 500 species, is the largest genus in the family ../Convolvulaceae/. The genus occurs throughout the tropical and subtropical regions of the world, and comprises annual and perennial herbaceous plants, viness, shrubs and small trees; most of the species are twining climbing plants. Many species are known as morning glory, a name shared with some other related genera. The genus includes important food crops (sweet potato and water spinach) and ../Ipomoea violacea/, source of the Mexican psychedelic drug, tlitliltzin. Species and cultivars of Ipomoea grown as morning glory are popular in gardens for their often stunning flowers. Description Flowers are regular and bisexual, with 5 sepals and a funnelform corolla with 5 lobes and stripes. The 5 stamens sit low in the tube, 1 style. The flower buds are "pleated", and open by untwisting. The fruit is a dry 4-6 valved capsule, containing as many seeds. Foliage is alternate, simple or compound. Most if not all temperate species are twining vines, with the stems containing a milky juice. Growing Conditions Most species require full sun.
