Green Alder

The Frank Hazelnut produces nuts that are medium size and ripen mid August. This is one of the best eating hazelnuts for cold climates. It is a medium size deciduous tree from Saskatchewan, Canada. It is a productive tree that has been tested as both a pollinizer and a main crop cultivar for colder climates. The Frank Hazelnut is one of the cold hardiest hazelnut trees on the market and known to be resistant to eastern filbert blight.

Not all hazelnuts pollinate with each other so it is important to pick the correct pollination pairs. Two compatible varieties of hazelnut are required to produce nuts. Nuts will only be produced once maturity is reached, around 2-3 years.

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.
