Ipomoea purpurea is a climbing much-branched plant and covered with long yellowish white hairs. It can measure up to 4 m long. The leaves are entire, large heart-shaped, pointed at the top. They are arranged alternately along the stem. They are widely stalked. They are slightly hairy above.The only hairy veins beneath. The flower is trumpet-shaped with wide variety of colors: blue, purple, pink or white. The fruit, globular in shape, is dry and contains black seeds shaped slice of orange.
Cotyledons are long petiolate, 1.5 cm. The blade of a generally square almost 1.5 cm square at right base slightly cordate, apex deeply emarginate to bilobed. Trinerved at the base.
Leaves are simple, alternate, petiolate. Base deeply cordate and top acuminate. Leave margin is entire, 3-5 palmate nerves from the base.
It is a climber, large vine highly branched, it grows up to 4 m long.
Deep taproot.
Stem is slender, cylindrical, slightly ribbed, voluble, covered with long white to yellowish hair reflected.
Leaves are simple, alternate, carried by a slender petiole, pubescent, 2 to 10 cm long and channeled to the upper part. Leaves are heart-shaped, 4 to 8 cm long and 3-5 cm wide, deeply cordate at the base, finely acuminate or obtuse at the top and slightly pubescent on the upper surface, the nerves hairy on the lower surface. The margin is entire. About 5-7 palmated nerves at the base.
Inflorescence is axillary in cyme supported by a slender peduncle, often longer than the petiole and with long reflected hair. Cyme with 1 to 5 flowers.
The median flower carried by a stalk puberulous pedicel 2 to 3 cm (with a puberulous bract at the base). The lateral flowers are shorter pedicellate. During fruiting, the stalks curl into a helix. Calyx with 5 sepals lanceolate, acute at the apex, scarious, hispid at the base, persistent. Corolla campanulate hairless, 2.5 to 5 cm long and 4-6 cm in diameter, 5 petals welded expanded tube. 5 stamens fused to the tube of the corolla. Assorted colors is blue, purple, pink or white.
Fruits are dehiscent capsules, spherical to ovoid shaped, 10 to 12 mm in diameter, greatly exceeded by the calyx. It may contain 6 seeds. It is brown at maturity.

Ipomoea purpurea and Ipomoea indica can be easily confused. Ipomoea purpurea is a vine not exceeding 4 m long, with generally entire leaves (unlobed), but rarely lobed, inflorescences usually containing 1 flower sometimes up to 4, the corolla of which is 4 to 5 cm long with color more often pastel (pink, blue, purple), while Ipomoea indica is a large liana that can easily reach 10 m long, has leaves of variable form often trilobed, dense inflorescences always containing several flowers and often more than 4, with corolla 5 to 7 cm long and of intense blue or violet color.
