River Birch
Seaside Arrowgrass

River Birch has beautiful, peeling, brown bark that reveals camel-colored and pink beneath. It is more borer resistant than white bark birches, which makes it a much longer-lived landscape tree.

Seaside Arrowgrass is a native perennial commonly found in wetlands, salt marshes, and moist meadows. It is especially suitable for difficult growing sites. Its dense root system helps stabilize soil, while also providing food, cover, and habitat for small animals within the wetland community.

Seaside Arrowgrass is suitable for shoreline stabilization, wetland restoration, and naturalization projects.
