Argyrochosma limitanea, the southwestern false cloak fern, is a species of fern native to the southwestern United States and Sonora, Mexico. It grows on calcareous rocks, and has small, finely-divided leaves with a leathery texture, dark axes connecting the leaf segments, and a heavy coating of white powder on the undersurface. It reproduces apogamously; two subspecies are recognized, which may have originated independently through the hybridization of other taxa not yet discovered. First described as a species in 1919, it was transferred to the new genus Argyrochosma (the "false cloak ferns") in 1987, recognizing their distinctness from the "cloak ferns" (Notholaena sensu stricto).
How to keep Argyrochosma Limitanea.
Pruning
In early spring, prune the southwestern false cloak fern to remove old fronds and encourage new growth. Use clean, sharp tools to trim the fronds back to the base. This practice supports the plant's natural growth cycle, encourages healthier and fuller growth, and helps maintain its aesthetic appeal.
