Description

Dryopteris intermedia is one of the rare ferns native to North America that is evergreen. And of those few, its deeply dissected blades and toothed leaflets provide it with the laciest texture of them all. This is not a particularly large fern. It has an elegant vase-like habit, with gently arching fronds that can grow from 1’ to 3’ long depending on site conditions. The underside of the leaflets on the fertile fronds is dotted with conspicuous sori (clusters of spore-containing pouches) that mature by mid-summer, and can be helpful in the identification of this species.

Cultivation

Intermediate woodfern is easy to grow, and trouble-free. It is adapted to part-shade or full shade, and moist, organically rich soil. It grows well under average conditions and will tolerate dry spells once established. It can be susceptible to crown rot if planted in a wet location or in poorly-drained soil. While the fronds are evergreen, they can be damaged by heavy snow. They can be cut back for aesthetic reasons late winter or early spring, before new growth begins to emerge. This is not an aggressive species, and although the root system is rhizomatous, plants tend to retain a tight clumping form. I can spread by spores in areas with consistent moisture throughout the year. It is very cold-hardy. Zones 3-8

Propagation

Propagate by division in spring or fall. Though more difficult, this fern may also be propagated by spores that typically mature by mid-summer.

Additional Notes

The genus Dryopteris (that includes about 250 species worldwide) is from the Greek words dryos, meaning oak or tree, and pteron, meaning feathered or wing-like (all ferns fall into the taxonomic division Pteridophyta). This is in reference to the fact that ferns of this genus are often found in woodlands, hence they are also commonly referred to as wooferns. The specific epithet, intermedia, means intermediate or in between. A probable reference to this fern being between (and easily confused with) Dryopteris carthusiana and Dryopteris campyloptera.
