Green Alder
Ussurian Pear (Siberian)

Green Alder is a native, cold-hardy shrub found in boreal forests, along slopes, and in open upland habitats. It fixes nitrogen in the soil, improving fertility and helping other plants grow, while its roots help stabilize slopes and disturbed ground. Fast to establish on poor soils, it is widely used in reclamation, restoration, and erosion control projects.

With its smooth grey bark and shiny green leaves, Green Alder often forms dense thickets that provide cover for birds and small mammals. Its seeds, buds, and catkins also supply food for wildlife. Green Alder is well suited for naturalization and ecological restoration.

Note: We use Green Alder for Alnus alnobetula subsp. crispa. This species is also known by many other common names, including Mountain Alder, Sitka Alder, and others. Please confirm the scientific name to ensure you are ordering the correct plant.

Ussurian Pear is the most cold hardy of all pear species. It is frequently used as a rootstock or as a pollinizer for other pear varieties. The pinkish-white flowers that bloom in the spring and the striking fall colours make it well-suited as an ornamental addition to your landscape.

Ussurian Pear can also be used for forming hedges as it tends to branch quite low.

While the Ussurian Pear is considered self-pollinating, planting with another pear variety will increase yields. Can be paired with Krazulya Pear or Beedle Pear.
