Brazil: Acanthospermum hispidum grows rapidly in the Estate of Sao Paulo, lasting 120 days from germination to fruiting. Flowering occurs from February to April and fruiting from March to May.
Northern Cameroon : Germination begins with the first significant rains at start of crop cycle (May). Flowering occurs very rapidly because the first capitullum appears at the branching point of the second pair of leaves. From June, the first alkenes are formed. Cultivation weeding practices such as plowing , weeding and mounding , cause new short phases of germination. These sprouts are even fewer that culture has a strong recovery . In regularly weeded plots , flowering and fruiting are delayed by 1 to 2 months . The plant dries in November, the start of the dry season.
China: Acanthospermum hispidum flowers from June to July and fruits from August to October.

Acanthospermum hispidum is an annual plant, it multiplies only by seed. Achenes are dispersed (Zoochoric dispersal) when they get caught in animal fur or hooves. This dispersal is greatly enhanced by the migration of animals in the early dry season. Dormancy is significant, and the percentage of germination at dipersal is very low (less than 1%). The viability of the seeds strongly decreases when they are more than 7 cm in depth.
