原生地・分布（英語）:

説明（英語）: Genus of about 200 species of terrestrial ferns found mainly in temperate regions of the N. hemisphere, where they grow in woodland, by streams or lakes, and among mountain rocks. Most are deciduous, but in mild winters some stay green in sheltered sites. Pinnate to 4-pinnate, sometimes pinnatisect fronds form "shuttlecocks" m most cultivated species. Spores are produced in kidney-shaped sori. The foliage looks effective with most herbaceous plants and shrubs; in frost-prone areas, grow tender species in a cool greenhouse.

耐寒性（英語）: Mostly fully hardy; some species are frost hardy or frost tender.

栽培（英語）:

繁殖（英語）: Sow spores at 15°C (59°F) as soon as ripe. Except in D. affinis, sporelings of cultivars differ in appearance from the parent. Divide mature plants in spring or autumn. See also p.51.

病害虫（英語）: Trouble free, but moth larvae may feed on spores.
