American Hazelnut
Hazels in their 4th growing season.
I planted two American Hazels (they were just twigs) in March of 2011. I think I paid $1 each. As the name suggests, they (or related species) grow wild throughout the US. Unlike most nuts, hazels (also called filberts) prefer to grow as a shrub, and seldom reach over 8 feet in height. This is their first year bearing nuts.
You can prune them to form a small tree, but they annually form multiple ground suckers, and want to be a bush.
You may have hazels on your property, or nearby. These wild hazels are unimposing, quite ordinary looking shrubs. The fruit is hidden. Last summer, while hiking a mountain bald along the Appalachian Trail, I noticed a vast stand of hazels at the margins, some reaching over 12 feet.
The fruit is usually well hidden by the foliage. One, two, or sometimes three nuts will develop within a single fruiting body.
The traditional method of harvesting hazelnuts is to wait for the husks to dry in the fall, causing the nuts to conveniently drop onto the ground. Unfortunately, squirrels and other critters know all about this. Often they will climb into the hazel and eat the nuts before they drop.
You can harvest them before the squirrels by waiting until you see brownish spots developing on the light green husk. Just twist the fruit off, and place them in a dry place for a month or so.
American hazelnuts are smaller than the European filbert sold in grocery stores.
Another fan of the American hazel.

EDIT: I forgot to mention that hazel leaves contain tannin. If you include a green hazel leaf into a batch of pickles, it will make them a little more crisp. Hazel leaves turn yellow or red in the autumn, making them attractive inside a pickle jar.
