distribution_en:

description_en: Genus of over 700 species of evergreen or semi-evergreen, terrestrial and epiphytic ferns found in diverse habitats on all continents except Antarctica. Short, erect, occasionally creeping rhizomes produce tufts of fronds, which may be simple, or pinnate to 4-pinnate, or pinnatifid. Some aspleniums are "bird’s-nest" ferns: striking epiphytes with long, entire fronds overlapping to form a "nest" in which organic matter collects. Sori are linear, and usually run parallel to each other from the midribs towards the margins of the fronds. Use smaller species in wall crevices, a rock garden, or an alpine trough. Grow larger species in woodland or among shrubs in a shady border. In frost-prone climates, grow tender species as houseplants or in a cool, temperate, or warm greenhouse.

hardiness_en: Fully hardy to frost tender. A. ceterach, A. scolopendrium, A. trichomanes, and their cultivars are hardy to -30°C (-22°F).

cultivation_en:

propagation_en: Sow spores as soon as ripe at 15°C (59°F) for hardy species, and at 21°C (70°F) for tender species. Divide’ hardy species in spring. Some species, such as A. bulbiferum, produce plantlets that may be potted up when 3 or 4 leaves have formed. See also p.51.

pests_en: A. scolopendrium is prone to rust in wet winters. Bird’s-nest ferns are vulnerable to scale insects.
