Seaside Arrowgrass

Black Spruce is a medium-sized coniferous tree that tolerates wet ground better than most spruces. It has a characteristic straight trunk and a narrow crown.

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.
