- Description
-
The silvery glade fern is an herbaceous perennial plant in the spleenwort family (Aspleniaceae). Its origin is eastern Canada and the eastern half of the U.S.A. Its native habitat is within and under the cover of forests. The specific epithet means “like Acrostichum,” which is an unrelated fern genus.
The fern requires constant moisture. It needs good loamy soil that retains moisture but also has good drainage. It is clumping but can spread via short creeping rhizomes. It will tolerate some sun with adequate moisture. The silvery glade fern clump grows 1 to 3 feet high and 1.5 feet to 3.5 feet wide. It grows in dappled to deep shade.
The fronds can reach over 3 feet at maturity. Fronds turn straw-colored in fall. The oblong sori form along the veins on the undersides of the pinnae and mature in late summer. The sori form a herringbone pattern.
This fern can be grown in naturalized areas, woodlands and in shade gardens.
