Seaside Arrowgrass
Tall Manna Grass

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.

Manna Grass and other waterside plants are an excellent way to prevent erosion and provide habitat and forage for animals. The difference is that Manna Grass looks better doing it! With distinctive purple grains at the top of its stalks, Manna Grass adds a splash of color to the waterside that most other aquatics can't offer.

Manna Grass is good for returning disturbed sites to nature and provides nourishment to many animals, except for cattle who find it toxic.
