Gray birch
Betula populifolia
A small, fast, short-lived pioneer birch of the Northeast with chalky white bark that does not peel, black chevrons below each branch, and triangular poplar-like leaves that flutter in the wind. It takes poor, wet or dry ground that other trees refuse, and is best used as a multi-stem clump where a quick screen or an early-succession look is wanted.
