Slender Wheatgrass
Seaside Arrowgrass

Slender Wheatgrass is a native perennial bunchgrass common across North America. It establishes quickly, making it effective for site recovery.

It produces upright seed heads that provide seasonal interest and seed for wildlife, and favoured for browsing by elk and sheep. Its seeds are eaten by birds and small mammals, and it provides cover for wildlife.

Slender Wheatgrass is among the first native grasses used for reclamation in western Canada and the U.S. It does exceptionally well in saline soils.

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.
