Habitat :Asplenium rhizophyllum is native to North America.
Asplenium rhizophyllum is a perennial fern consists of a small tuft of low simple leaves. The leaf blades are 2-12″ long and ¼–2″ across; they are lanceolate or linear-lanceolate, often with tips that are very slender and long. The base of the blade is either cordate or it may have a pair of eared basal lobes (auriculate); the margins are smooth and slightly undulate. The upper blade surface is medium to dark green and glabrous, while the lower surface is pale green; occasionally there is some sparse pubescence. The slender stipes are shorter than the blades and about ¼–4″ in length. They are brown at the base, becoming green where the stipe joins the blade. Fertile and infertile leaf blades are similar in appearance, except the former is often longer than the latter. The sori (spore-bearing structures) are located on the undersides of fertile leaf blades; they are scattered irregularly across the lower surface at the vein junctures. The small sori are elongated in shape with laterally attached indusia (protective membranes). The tiny spores of the sori are released during the summer or fall and distributed by the wind. The root system consists of a short rhizomatous crown that produces the leaves and slender fibrous roots. This fern can reproduce vegetatively when the tips of the leaf blades root into the ground, developing new tufts of leaves around the mother plant. As a result, vegetative colonies of plants are often encountered.
This fern prefers light to dense shade, moist humid conditions, and thin rocky soil. It requires a sheltered location where it gets protection from the wind.
