Seaside Arrowgrass
Canada Mint

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.

Canada Mint is a native perennial plant known for its fragrant edible leaves. It produces small white to purple flowers in clusters around the stem and is commonly found in wet areas, including ditches and along wetlands, lakes, and rivers. The leaves can be eaten fresh or used to make teas and essential oils.

Canada Mint can spread quickly through underground rhizomes, making it well-suited to naturalization and restoration projects where it can spread freely. In smaller urban yards or gardens, container planting is recommended to help manage its growth. If planted directly in the ground, regular care and maintenance may be needed to limit its spread.
