American Hazelnut/Filbert
Sea Buckthorn (Seaberry)

American Hazelnut is a cold hardy, disease resistant, and long-lived nut tree. It is a great choice for a shrub border for wide, open spaces where it will be allowed to spread. Typically used in naturalization projects for its spreading nature, American Hazelnut is ideal for our zone 4 customers.

If you're a zone 3 prairie customer, don't worry! American Hazelnut can still thrive but needs additional care and protection from our harsh prairie climate.

The edible nuts mature from September to October and are usually roasted or eaten fresh. Make sure you take time to notice American Hazelnut's variable and beautiful fall color that ranges from orange, rose, purplish-red, yellow, and green.

Note: You want more than one hazelnut to improve yields.

Sea Buckthorn, aka Seaberry, is a nitrogen fixing shrub that produces attractive berries high in vitamin C.

While we can't confirm claims that the berries are effective in treating various ailments, many people believe consuming the berries helps with arthritis, infections, and asthma, among other things.

Sea Buckthorn plants have attractive pale silvery-green leaves, dense branches, and large thorns, people like to grow in ornamental hedges or as a first row in a shelterbelt.

Note: Sea Buckthorn is dioecious, meaning male and female flowers grow on separate plants. Both are required for fruit production, though only female plants bear fruit. A plant’s sex typically cannot be identified until its third or fourth year. Our seedlings are too young to determine their sex.
