Shield Fern

Dryopteris carthusiana (dry-OP-ter-iss kar-thoo-see-AY-nuh)

Family: Polypodiacea Native Herbaceous (1-3 ft)

The spinulose woodfern is an herbaceous perennial fern in the polypody family (Polypodiaceae). It is widespread across the northern hemisphere and occurs naturally, but uncommonly, in North Carolina. The species epithet is derived from the Latin name for the Chartreuse Mountains in the French Prealps and honors the place from whence this fern was first described. This fern is easy to grow and grows naturally in swamps and wet woods in full or partial shade. It grows well in organic loamy soil. It prefers moist, well-drained, acidic soil. It can be propagated by division or spores. This fern does well in moist woodlands, especially near streams. It would be a good choice for a native plant garden or a shade garden.
