Dryopteris is a genus of woodland ferns known by a variety of common names including wood fern, autumn fern, shield fern, and buckler fern. Most Dryopteris die back to the ground in winter, but in mild winter regions, some stay green in sheltered spots.

Dryopteris are erect growing ferns to about 2 feet tall; their form is similar to a shuttlecock. The fronds are pale green and lance-shaped.

Dryopteris grow best in partial shade with moist, well-drained soil rich in organic matter. They thrive in evenly moist to wet soil. Two species, D. affinis and D. filix-mas, tolerate considerable sun provided soil moisture is consistent.

Dryopteris are a good choice for shade and woodland gardens. Their fronds are a good contrast to perennials and shrubs with coarse. large leaves.

Dryopteris is a genus of more than 100 species. Dryopteris are found in temperate regions of the Northern Hemisphere around the world. and Only a few are generally offered by nurseries.
