Diablo Ninebark
American Hazelnut/Filbert

Diablo Ninebark is a small, low maintenance, multi-stemmed shrub, that is used to add texture or color to any yard. This plant grows dark purple leaves in the spring and grows slightly faster than Common Ninebark. It features flaky red to brown bark, clusters of white flowers, and long, maple-like leaves. Diablo Ninebark can make a dense and colorful hedge, or it can be an attractive ornamental by itself.

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.
