Water birch is a graceful, multi-stemmed small tree or large shrub with dark, reddish-brown bark (rather than the white bark of paper birch), typically found lining streams, wetland edges, and other consistently moist ground. Dangling catkins appear in spring before the leaves, offering early pollen for emerging pollinators. Fast growing and well suited to wet feet, it’s a great choice for streambank stabilization, riparian restoration, or anywhere you need a tough, moisture-loving tree with year-round structure.
