Seaside Arrowgrass
Gray Dogwood

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.

Gray dogwood is a thicket-forming, deciduous shrub with greenish-white blossoms in open, terminal clusters. Young twigs are red and the fruit pedicels remain conspicuously red into late fall and early winter.

Fruit itself is a white, 1/4 in. drupe that usually does not remain on the shrub for long.

Great for naturalizing wild areas, this shrub attracts birds and other wildlife.
