A small growing species from China with attractive fimbriated pinnules. The Flora of China says: "On rocks by streamsides; 1100-3400 m. Gansu, Guizhou, Hebei, Henan, Shaanxi, Shanxi, Sichuan, Yunnan." Sue Olsen says: "Adiantum davidii (after Father Amand David, 1826-1900) from China (where web searches translate the name as "pig long neck hair grass") and Tibet has triangular 6- to 12-in. (15- to 30-cm) bipinnate fronds on a blue-black wiry structure. The pinnules are undulate wedges of soft green with spine-tipped terminal margins. Sori with inrolled, kidney-shaped false indusia are connected in pairs at the apex of each pinnule. The species, evergreen in warmer areas and deciduous in cold regions, is similar to A. venustum and distinguished by the more incised pinnule margins. It is cultivated in Zone 6 gardens in Germany as well as warmer gardens in England. When available, it should be an instant success with fern growers in the United States, especially the dedicated specialists looking to expand their hardy maidenhair collections in Zones 6 to 9." |
