Ipomoea indica is a twining, occasionally prostrate, herbaceous plant that is more or less densely tomentose on the axial parts with backward-facing trichomes . The stems can be 3 to 6 cm long and sometimes take root at the nodes . The leaves are stalked with 2 to 18 cm long petioles . The leaf blade is ovate or round, 5 to 15 cm long and 3.5 to 14 cm wide. The underside is densely hairy with short, soft trichomes, the top is more or less sparsely hairy. The base is heart-shaped, the leaf margin is entire or three-lobed, the tip is pointed or sharply pointed.
The inflorescences are dense, umbel-shaped cymes from a few flowers . The inflorescence stalks are 4 to 20 cm long. The bracts are linear or sometimes lanceolate. The flower stalks are 2 to 5 (rarely up to 8 mm) long. The sepals are almost identical, 1.4 to 2.2 cm long and slowly pointed to a ruler. They are hairless to closely tomentose, the outer three sepals are lanceolate to broadly lanceolate, the inner two are narrowly lanceolate. The crown is funnel-shaped, 5 to 8 cm long, hairless, bright blue or bluish purple, with age they become reddish purple or red. The center of the crown is a little paler. The stamens and pistil do not protrude beyond the crown. The ovary is hairless. The scar is three-lobed.
The fruits are more or less spherical capsules with a diameter of 1 to 1.3 cm. The seeds are about 5 mm in size.
