Dr. Thomas R. Nasser, III (Tom): Sweet Birch

Sweet Birch (Betula lenta)

Sweet Birch is native to forests all along the Eastern United States from Maine down to North Carolina. It likes full sun though it will certainly grow in some shade. When mature this tree can easily reach 40 – 50 feet in height. The bark of the sweet birch smells strongly of wintergreen. and historically the twigs were used for birch beer, a drink very similar in taste to root beer.
