Diablo Ninebark
Andrew Hazelnut

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.

Andrew Hazelnut is a northern cultivar that is grown specifically for its cold hardiness. Typically, hazelnuts produce smaller nuts in colder climates, but for Andrew Hazelnut, this is not the case.

This hybrid variety is incredibly productive, growing medium sized nuts that ripen in late August. Pair with another Andrew or Aldara Hazelnut for cross pollination to occur.

The edible nuts can be eaten fresh, used in baking, and will make a beautiful hedge. Andrew Hazelnut is also eastern filbert blight resistant.

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