JAPANESE SILVER GROSSES
Silver grass is a species of perennial flowering plant native to Japan. Its leaves are oblong or ovate, with five leaflets each measuring 2-5 cm long. They have two narrow white teeth at the tip of each leaflet, which allow them to grasp onto twigs and other plants when they are young.
Leaves turn yellowish brown and eventually drop off completely after several years of growth. When silver grass flowers, it produces a pinkish flower spike. Silver grass grows best in moist soil and prefers full sun. It is not frost hardy but can survive temperatures down to -10°C (-20°F).
The Japanese silvergrass (Agrostis albidum) is one of the most widely cultivated plants in Japan. It is used for its edible leaves, which are eaten raw or cooked. The leaves are often added to soups and stews, where they add a distinctive flavor.
Other uses include tea infusions and medicines such as cough syrup.
In addition to being consumed, silver grass is grown commercially for its seeds. These seeds produce small silver-colored berries that can be ground into flour or used like cornmeal in baking recipes.
Silver grass contains a number of nutrients, such as B vitamins and dietary minerals. It also contains proteins that can be used food additives (such as texturizers) for manufacturing processed foods.
DISTRIBUTION AND HABITAT OF JAPANESE SILVER GRASSS
The natural distribution of silver grass is restricted to eastern Asia: Japan, Korea and parts of China. Outside its native range, it has been introduced to various other regions around the world.
In its natural environment, silver grass grows in wet mountain forests and stream banks. Its roots are shallow, allowing it to anchor itself in the mud while its shoots reach for the sunlight. Young shoots are eaten by deer and other grazing animals, while mature plants are browsed by forest cattle.
It is an important food source for the endangered Japanese serow (Capricornis crispus).
Silver grass requires a mild climate with lots of rainfall to thrive. It is not frost hardy, and is often cultivated in container gardens in colder climates. It prefers growing in rich, loose soil that is constantly wet.
NATIONAL AND INTERNATIONAL CONSERVATION STATUS OF JAPANESE SILVER GRASSS
The Japanese silver grass is currently not threatened or endangered throughout its native range. It is widespread across its natural environment of Japan and China, and its range extends into Korea.
