Bog Birch
Pygmy Caragana

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.

Pygmy Caragana is a shrub that is related to Common Caragana and has a compact size that is suitable for yards with limited space. Its size is perfect for landscaping and decorative hedges, and requires little maintenance. This nitrogen fixer has fine-textured foliage and small yellow flowers. Much like Common Caragana, it is hardy and drought tolerant.

Popular as a low maintenance commercial landscaping shrub and for hedging. This species does have tiny spines that might poke you a bit. It has a nice appealing texture when mature.
