Buds and one flower of American bittersweet. This plant is a particularly fine example of American bittersweet, in that it has large clusters of flowers only at the ends of stems. In contrast, oriental bittersweet (Celastrus orbiculatus) has two or three flowers above each leaf in stretches along the stems. Photographed in Bruce County, Ontario in early June.
