Northern Cameroon: Ipomoea coptica is observed throughout the rainy season. Germination takes place in early July and the first flowers appear in August. Fruiting occurs in September till drying of the plant early in the dry season. Cultivation operations are followed by few new seedlings.
Madagascar: I. coptica blooms as from the middle of the rainy season.

Northern Cameroon: Ipomoea coptica is mainly a species of Sahelo-Sudanese region, where annual rainfall is between 600 and 800 mm. It is characteristic of sandy soil on the surface but with a perched water table such as ferruginous soils of dunes and sandy banks along the river.
Madagascar: The species grows on ferruginous soils more or less humiferous (temporary waterlogging), in natural pastures and abandoned fields. It is a weed of rainfed crops in semi-arid and low altitude sub-humid area of plains. It grows on fairly fertile soils, in sunny or lightly shaded land in cultivation systems of cotton or maize, semi-intensive of agro-ecological semi-arid zones (Southwest and West) and low altitude sub-humid areas (North-west plains).

Local harmfulness
Northern Cameroon: Ipomoea coptica is an infrequent weed but can be locally abundant and is a good environmental indicator. It grows in low intensified cultures, receiving no or little fertilizer and no herbicide. It is also present in young fallows.Attributions | Wiktrop |
