Dryopteris intermedia is a wonderful North American native evergreen fern that can be found in mountainous regions from Canada south to Alabama. The 2' long fronds make an 18" tall x 3' wide clump that grows best in moist woodland locations, where it has a slight preference for alkaline soils. Research has shown Dryopteris intermedia to be overly promiscuous, having fathered offspring with at least eight other wood ferns...creating quite a taxonomic and legal tangle as you can imagine.
