plant sale text: Log fern, found in swamps and calcareous floodplains of the Eastern U.S., produces large, upright fronds whose dark green color and elegant shape add a beautiful lushness to shady parts of a home landscape. A naturally occurring, fertile hybrid between D. goldiana and D. ludoviciana, log fern is semi-evergreen. It is often found growing on rotting logs (hence its common name).
