Adiantum jordanii is a perennial species Pteridaceae known by the common name California maidenhair. It is native to California and Baja California. It grows in shaded woods, usually in wetter spots such as moist rock outcropping and lower parts of north facing slopes. It can take a little sun near the coast or full shade inland. Each trailing leaf may reach over half a meter in length and is made up of many rounded green segments. Each segment has two to four lobes and it may split between the lobes, the underside of each segment bearing one to four sori. It remains evergreen with regular water or will go dormant if allowed to dry out in summer but should recover. It forms a slowly expanding clump. Adiantum jordanii is a host for the Sudden Oak Death pathogen, and for this reason it may be difficult to find in native plant nurseries.
