About
Alderleaf buckthorn is a bushy fruiting shrub found on riverbanks, meadows, and moist areas. Its native habitat is southern Canada and Northern United States; unlike the invasive buckthorn (Rhamnus cathartica).
The leaves are narrowly ovate to narrowly elliptic and granular toothed. Stems are gray and smooth. Small green shallowly bell-shaped flowers appear on the from June to July. They're either solitary or in umbels (of up to three) and are either male or female (dioecious). Bluish-black three seeded berries follow (drupes). The flowers and fruit attract wildlife such as birds, butterflies and moths.
