The white flowers are produced in spring in a dense raceme about long. Its most striking feature is its fruit, a diameter white berry, whose size, shape, and black stigma scar give the species its other common name, "doll's eyes". The pedicels on which the berries grow are thicker than those of the related species, red baneberry ("Actaea rubra"). This is the reason for the specific name "pachypoda", which means "thick foot", from Ancient Greek "thick" and "foot". The pedicels thicken and become bright red as the berries develop.
