description_en: Genus of nearly 200 species of usually evergreen, terrestrial ferns found in a range of habitats from alpine cliffs to tropical forests worldwide. They are cultivated for their often lance-shaped, pinnate to 3-pinnate fronds, which arise from erect or short-creeping rhizomes, usually in shapely, "shuttlecock" crowns. The pinnae are holly-like, and some-times lobed, each lobe ending in a sharp point or bristle. Sori are borne on the undersides of the fronds, each usually protected by a rounded indusium. Grow shield ferns in a rock garden, fernery, or well-drained border. In frost-prone areas, grow tender species In a cool, temperate, or warm greenhouse.
