Bog Birch
Empress Tree

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.

The Empress Tree is a fast growing, ornamental shade tree. It has purple, fragrant flowers that are quite attractive. The flowers emerge before the leaves in early spring. The leaves of this tree can grow very large, up to 30 cm long.

As one of the fastest growing trees in the world, this tree has been given considerable attention for carbon sequestration projects. It drops many seeds which can make it invasive in warmer climates. Please do some research and plant the right tree in the right place.

The Empress tree’s genus name comes from Princess Paulowna, daughter of Tsar Paul I of Russia.
