Bog Birch
Black Gum

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.

Black Gum is a slow-growing ornamental shade tree with a dense pyramidal shape. The foliage is dark green in the summer, and transitions to bright fall colours which include red, orange, purple, and gold. It is commonly used as an ornamental tree in parks and large gardens as a specimen or shade tree.

The small greenish white flowers provide nectar for bees and black tupelo honey is a sought after flavour. The small dark blue fruits which ripen in late summer will attract birds and other animals to your yard. The fruits are edible, but very sour, and are primarily used for pies, flavouring, and drinks. Plant the Black Gum where it will live long-term, as it has a large taproot and does not transplant well.
