Intermediate Wood Fern Dryopteris intermedia

Phonetic Spelling
dry-OP-ter-iss in-ter-MEE-dee-ah
Description

The Evergreen Wood Fern is easy to grow.  As its common name refers, its fronds are evergreen to semi-evergreen in climates that experience mild winters.  In locations where it is not evergreen the old fronds should be removed during the winter months before the new spring growth begins.  It prefers moist, shady sites but will tolerate dryish conditions on a short term basis.  This fern does not spread.  Plant in an area protected from strong winds that may damage the fronds.  

It is native to moist wooded areas, ravines, swamp edges and rocky slopes of Eastern North America.  

Caution should be used to prevent the soil from drying out.
