Green Alder
Ussurian Pear (Siberian)

Green Alder is a cold hardy, native shrub. It is often planted on infertile sites so it can fix nitrogen from the air and improve the soil quality.

Green Alder is known for its smooth grey bark and attractive shiny green leaves; it is commonly used in reclamation.

Ussurian Pear (aka Manchurian or Siberian Pear) is the most cold hardy of all pear species.

This self-pollinating pear bears white flowers in the spring and has good fall colour, making it an exceptional ornamental addition to any garden. However, it has a tendency to branch quite low and is often used in shelterbelts and hedges too.

It is primarily grown for its attractive flowers and pollination of other pear varieties, or as cold hardy rootstock, and is also an excellent addition to any shelterbelt.
