What is Asplenium nidus
Asplenium nidus or Bird's Nest Fern (Asplenium nidus) is a species of evergreen fern in the family Asplenaceae, native to Japan, Taiwan and China. It produces long, radiating leaves from a short stem. The leaves resemble kelp and are glossy with folds, and the veins extend straight down the center and are slightly concave. The sporangium is attached to the tip of the leaf and about halfway across. The central part of the radial plant has a structure that allows water and fallen leaves to accumulate, creating a humus that is used for nourishment. It is also called Bird's Nest Fern. The new shoots are eaten as a garnish for Ohitashi, miso soup, stir-fries, etc., and are also used as flower material for flower arrangement. Since it is a fern, it does not bloom. There is another fern in the same genus, Asplenium antiquum. A. antiquum has a large number of spores on the underside of its leaves, while A. nidus has only spores on about half of the leaf width, and only one third of the leaf length from the tip.
