Summer green ferns (wilt in winter) found in forests and grasslands from hills to mountains. Prefer wet areas and often found near streams and ditches. Young leaves are create spiral shape and covered by hair, this resemble old coin called zenmaki and changed to the current Japanese name Zenmai. Flat spiral spring, zenmai-bane used in machines is named after this plant. It is one of the popular plants in wild plants to eat but young leaves of trophophyll (leaves for photonic synthesis) and spore leaves (leaves with spores) are too hard to eat. Trophophyll grow up to about 50 cm, yellow-green and soft with toothed margins (edges of leaves are like a teeth of saw). Parallel leaf veins become visible when looking at plants through the sun. Spore leaves are stick-shape and green become brown when ripen and wilt in early summer.
