Status:

The range of Sweet Birch is mainly northern and along the Appalachians. In Maryland, it is mostly limited to the western half of the state in the Piedmont and mountain zones, is absent from the eastern shore and rare in southern Maryland (Brown and Brown, 1972).

Description:

The bark of Sweet Birch is a helpful identifying characteristic. It is dark (gray to nearly black). It eventually breaks up into large, thin, irregular, scaly plates. Horizontal lenticels are usually noticeable. The bark can sometimes be confused with that of Yellow Birch, but does not exfoliate to the extent that Yellow Birch bark does.

Relationships:

Suspected host plant for Chocolate Prominent Moth (Miller et al., 2018).
