This widespread, mainly temperate northern hemisphere fern genus
includes some 75 species. They may be epiphytic or terrestrial and a
few species grow on rocks. They have scaly, red-brown, creeping
rhizomes and long-stemmed, light to mid-green, pinnate or bipinnate
fronds usually less than 30 in (75 cm) long. They are inclined to
produce cristate fronds and other unusual forms, which were very
popular with Victorian collectors.
Plant Height From approx. 30 To 60 cm
Cultivation: Hardiness varies considerably with the species,
otherwise they are easily grown in any moist, well-drained soil in
dappled shade. Additional humus promotes lush foliage. Propagate by
division or by sowing spores.
