Bog Birch

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.

Bog Birch is a hardy, deciduous shrub native to North America. It thrives in wetlands, riparian zones, and boreal forests, and can be found as far north as the Arctic Circle—making it one of the few woody plants to grow in such extreme climates.

In Western Canada, it is especially common in moist lowlands, along streambanks, and in peatlands. Beyond its ecological role in stabilizing soils and supporting wildlife, Bog Birch is frequently used in reclamation and restoration projects due to its resilience and ability to establish quickly in disturbed or degraded landscapes.

Note: We use Bog Birch for Betula pumila. This species is also known by many other common names, including Dwarf Birch, Swamp Birch, and others. Please confirm the scientific name to ensure you are ordering the correct plant.
