There are four general geographic zones for the occurrences of native ferns in nature and for the the adaptability of naive ferns for gardens: High Mountains, Low Mountains to Inner Piedmont, Middle to Outer Piedmont, and Coastal Plain. These zones are roughly parallel in South Carolina (to the Fall Line). In North Carolina the zones are highly variable in shape because of significant elevation differences, higher Latitude. and more complex climate patterns. Although many native fern species occur throughout the Carolina, some species occur only in one or a few zones. Follow the links below for details about lanscaping with native ferns.
