Northern Cameroon: Ocimum americanum germinates in June, when the rains are regular and that the soil has sufficient water. The germination is of short duration (1-2 weeks). Flowering occurs as from July, followed by fruiting in August. It ends at the beginning of the dry season (November) with drying of the plant.
Mayotte: Ocimum americanum flowers and fruits all year round.

Northern Cameroon: Ocimum americanum is a ruderal species that grows in humid marshland and areas of household discharge near villages. This is an infrequent weed. It grows on silty clay wet soils as the alluvium along water streams, vertisols of floodplains and planosols. It is found from the Sahelo-Sudanese regions to Sudanese regions. This species resents competition from other species and repetitive weeding. Moreover, it is very sensitive to herbicides. It occurs most often on the edge of land in vegetable crops or traditional lowland rice fields.
Comoros: Species present along the roads, especially in areas of low altitude in the three islands.
Madagascar: Species characteristic of humid lowlands or temporarily flooded during the rainy season (often fertile soil: alluvial soils, vertisols, ferruginous hydromorphic soils) in hot area of low elevation. It grows in quite late cultures to become dominant in the mid or end of the cycle, in fallow or bare soil after the withdrawal of flood waters.
Mauritius: plant grown along roadsides, rock gardens, fallow. It is present in Port Louis and the River des Galets.
Mayotte: Ocimum americanum is a cryptogenic species with two forms. The typical form is spontaneous in secondarized habitats, crops, wastelands, hydromorphic soils, villages, degraded forests, from the xerophilic coast to the heights. The form "pilosum" is cultivated for its condiment and medicinal uses and is also found in a spontaneous state in the same environments.
Reunion: Absent.
Seychelles: Present in clearings and abandoned places, rarely abundant.
