Flowering and fruiting: March-July
Vitex species flowers are complete, bisexual, i.e., with functional male (androecium) and female (gynoecium), including stamens, carpels and ovary. Pollination is entomophilous i.e., by insects. Flowering/Fruiting: March-September.
Direct sowing of seeds.
Seeds dispersed by barochory i.e., gravitational dispersal, zoochory i.e., dispersal by birds or animals.
In panicles from terminal and upper leaf axils; blue to purple. Flowering from June-September.
A globose drupe, fleshy, purple when ripe. Fruiting from October-January.
Bark yellowish-grey. Rachis and petioles winged in young plants.

Fruit drupaceous, globose, about 1 cm in diameter, green, glabrous, purplish black when ripe, fruiting calyx cupular, pubescent, seeds nonendospermous.
