The fruit of Ipomoea bathycolpos is a globose capsule, here green and clasped by the five narrow sepals that have by now turned a dull, brownish pink colour. The fruit dehisces to release about four seeds.

Ipomoea is the genus to which the sweet potato also belongs, but I. bathycolpos lacks edible tubers (Van Wyk and Malan, 1997; iSpot).
