Myōga (茗荷) or myoga ginger (Zingiber mioga, Zingiberaceae) is an herbaceous, deciduous, perennial native to Japan that is grown for its edible flower buds and flavorful shoots. Flower buds are finely shredded and used in Japanese cuisine as a garnish for miso soup, sunomono and dishes such as roasted eggplant.
As a woodland plant myoga has specific shade requirements for its growth. It is frost-tolerant to 0F, -18C possibly colder.
There is an old saying in Japan that eating too much myoga makes you forgetful or stupid.
