Dwarf-Bog Birch is a native, cold-hardy shrub that can be found across most of Canada. Its preference for moist soils and the extensive root system make it well-suited for riparian zone plantings, soil stabilization, and erosion control projects.
It features small, round, leathery leaves with scalloped edges and produces small, cone-like catkins. A distinguishing characteristic of the Dwarf-Bog Birch is the presence of large resin glands on the branches and the undersides of the leaves. These resin glands are the reason for its scientific name, Betula glandulosa.
Note: We use Dwarf-Bog Birch for Betula glandulosa. This species is also known by many other common names, including Bog Birch, Dwarf Birch, Glandular Birch, and others. Please confirm the scientific name to ensure you are ordering the correct plant.

Black Hawthorn is a versatile plant that is native to wetlands and other areas with moist soils, but can also tolerate dry soils. This plant can be grown as a short shrub, or a tree reaching 30 feet tall.

Black Hawthorn is valued for erosion control and attracting pollinators. It also makes an attractive flowering ornamental that can be planted as a specimen or pruned as a hedge. It is commonly used in shelterbelts.
