American Hazelnut is a thicket forming shrub that works well as a privacy screen. C. americana is a monoecious shrub, meaning both male and female flowers occur on the same plant, unlike others such as Spicebush, where you would need a male plant and a separate female plant in the vicinity in order to pollinate the fruit.
In the spring, the American Hazelnut male flowers produces long yellowish catkins that flutter in the breeze, and the female reddish catkins form green bell-shaped flowers, from which the edible hazelnuts appear. 3-5 shrubs are recommended for optimal nut production.
This shrub is very interesting in the Fall with great variants in foliage color. The American Hazelnut supports over 140 species of butterflies and moths, as well as mammals both small and human-sized.
ECO-TYPE: Some local eco-type, some grown from seed collected in New Hampshire. Started by New Hampshire State Forest Nursery.
