Pygmy Caragana
Dwarf-Bog Birch

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.

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.
