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.

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.
