Beach vitex is a perennial that grows throughout the summer months in temperate and tropical areas of the Pacific. In temperate areas, the plant is deciduous and loses its leaves during the cool nights of fall. In the southeastern United States, leaves emerge in April while flowering occurs from June–August with fruiting following shortly thereafter. Fruits may remain attached to the plant into the early spring. V. rotundifolia is capable of overwintering on the dunes in South and North Carolina and in gulf coastal areas. It can survive in USDA hardiness zones 6b to 10.
