Betula lenta (Sweet Birch)

Aromatic and long-lived (100 years or more), Betula lenta (Sweet Birch) is a single-trunked, medium-sized deciduous tree of conical habit in youth, becoming oval to rounded with age. Its ascending branches are covered with ovate, serrated, shiny leaves, 2-6 in. long (5-15 cm). Emerging light green in spring, the foliage turns dark green as the season progresses before turning rich golden yellow in fall.

Aromatic and long-lived (100 years or more), Betula lenta (Sweet Birch) is a single-trunked, medium-sized deciduous tree of conical habit in youth, becoming oval to rounded with age. Its ascending branches are covered with ovate, serrated, shiny leaves, 2-6 in. long (5-15 cm). Emerging light green in spring, the foliage turns dark green as the season progresses before turning rich golden yellow in fall. The flowers are small, tan catkins, 3 in. long (8 cm), that appear in spring before the leaves unfurl. They provide pollen for bees and other insect pollinators. Sweet Birch gives off a sweet fragrance when leaves, shoots, or bark are crushed. Smelling and tasting of wintergreen, the bark is quite appealing. Thin and reddish-brown in youth, it becomes dark gray with vertical, scaly plates with age. In winter, its delicate branching reveals the alternating, pointed buds and delicate catkins. Sweet Birch is a wonderful plant for wildlife. It attracts caterpillars and provides food for migrating birds in spring and fall. Attractive in all seasons, this superb eastern North American native is an excellent specimen tree and is also useful for lawns and naturalized areas. Performs best in cooler climates.
