Alderleaf Buckthorn

Scientific name

Rhamnus alnifolia


The Alderleaf Buckthorn is a small, deciduous shrub species that can grow about 1 m tall. This species produces a full crown with all branches arising from one main stem. The leaves are alternately arranged, green, 3-10 cm long, egg shaped with a pointed tip, and have toothed edges. The flowers are greenish yellow color, 5 mm wide, and found in stalkless, flat-topped clusters on lower leaf joints that bloom in late spring. These flowers produce berries in the fall that are bluish black in colour, 6-9 mm wide, with flat hard seeds inside. This shrub species prefers to grow in wet or moist conditions, and can tolerate a range of sunlight exposure. It is naturally found in wet forests, wet meadows, marshes, and along lake or stream shorelines. The Alderleaf Buckthorn produces very small, green flowers which bloom late in the spring, turning to dark berries during the fall. These berries are poisonous to humans.
