- Description
-
Log fern is a semi-evergreen to evergreen native fern in the wood fern family (Polypodiaceae) native to central and eastern United States and is found growing in moist woods and swamps. This species is a fertile allotetraploid derived from the hybridization of D. goldiana and D. ludoviciana. The Genus name is from the Greek dryas, meaning oak and pteris, meaning fern, referring to some species of wood ferns found in areas populated with oaks.
This fern grows upright to 3 to 4 feet tall and will spread 2 to 3 feet wide, spreading by creeping rhizomes. It prefers partial sun to shade in moist to wet soils with a slightly acidic to neutral pH.but will also tolerate drier sites such as decomposing wood. Propagate by division as needed.
The fronds of this fern are dark green, moderately cut and lanceolate in general outline. They grow 18 to 20 inches long and 8 to 9 inches wide. The fertile fronds have sori that are rounded and in rows. Ferns in this group hybridize with each other making identification problematic in some cases.
Use this fern in groups or borders of shade, woodland, native and winter gardens.
Insects, Diseases, and Other Plant Problems: No significant problems.
