Ipomoea is the largest genus in the flowering plant family Convolvulaceae, with over 500 species. It is a large and diverse group with common names including morning glory, sweet potato, bindweed, moonflower, etc. The most widespread common name is morning glories, but there are also species in related genera bearing the same common name. Those formerly separated in Calonyction (Greek καλός, kalos, good and νύκτα, nycta, night) are called moonflowers. The generic name is derived from the Greek words ιπς (ips) or ιπος (ipos), meaning "worm" or "bindweed," and όμοιος (homoios), meaning "resembling". It refers to their twining habit.
The genus occurs throughout the tropical and subtropical regions of the world, and comprises annual and perennial herbaceous plants, lianas, shrubs and small trees; most of the species are twining climbing plants. Ipomoea tricolor (morning glory) is native to the New World tropics, and widely cultivated and naturalised elsewhere. It is an herbaceous annual or perennial twining liana growing to 2–4 m tall. The leaves are spirally arranged, 3–7 cm long with a 1.5–6 cm long petiole.
The flowers are trumpet-shaped, 4–9 cm in diameter, most commonly blue with a white to golden yellow centre.In cultivation, the species is very commonly grown misnamed as Ipomoea violacea, actually a different though related species. Numerous cultivars of I. tricolor with different flower colours have been selected for use as ornamental plants; widely grown examples include Blue Star, Flying Saucers, Heavenly Blue, Heavenly Blue Improved, Pearly Gates, Rainbow Flash, Skylark, Summer Skies and Wedding Bells. The cultivar 'Heavenly Blue' has gained the Royal Horticultural Society's Award of Garden Merit.
