'''''Ipomoea tricolor''''' is a species of [[Ipomoea|morning glory]] native to the [[New World]] [[tropics]], and widely cultivated and [[naturalisation (biology)|naturalised]] elsewhere. It is a herbaceous [[annual plant|annual]] or [[perennial plant|perennial]] twining [[liana]] growing to 2-4 m tall. The [[leaf|leaves]] are spirally arranged, 3-7 cm long with a 1.5-6 cm long petiole. The [[flower]]s are trumpet-shaped, 4-9 cm diameter, most commonly blue with a white to golden yellow centre.
In cultivation, the species is very commonly grown mis-named as ''[[Ipomoea violacea]]'', actually a different though related species.

Ipomoea tricolor, Cav. (I. rubro-caerulea, Hook. I. hookeri, Don and Hort.). St. tinged with purple, branched, 10-20 ft. high: lvs membranaceous, much-veined, short-acuminate: peduncle hollow and wand-like, longer than petioles, 3-4-fld.; fls. 3-4 in. wide, the tube white and limb red before expanding, at length purple or china- blue. Aug.-Oct. Mex. R.H. 1855:441 (as Pharbitis rubro-caerulea). B.M. 3297. P.M. 3:99. Gn. 27:72. G.C.III.53: 104.—One of the most beautiful of annual climbers. The fls. are often dashed, blotched and shaded with rose, or are entirely rose. It is likely to run to vine when out-of-doors unless the roots are confined in a box or pot to induce early flowering. It makes an excellent pot-plant for the greenhouse. Var. Heavenly Blue, from Calif., proves to be a blue form of I. tricolor, which is especially valuable for cut-fls. Var. alba, Hort., has pure white fls.
