Corylus americana

Native, globular or mound-form deciduous shrub 8-15' tall, which frequently suckers into thickets. It usually has a dense mass of many stems that are upright and spreading. Suited for restorations, slope stabilizations, and mass plantings. It is useful for borders and soil stabilization because of its colonial tendency.
