雨がかからず、適度な湿気を保たせ、10日以上の晴天が続くことが必要条件。偶然の産物と称されるほど希少価値が高く、出荷量が椎茸生産量の1%にも満たない為、市場にはほとんど出回りません。椎茸の傘の部分がひび割れ、その白い亀裂が名前の通り花のように見える、上級品です。
普通の冬菇に比べて味や香りが豊かであり、流通量も少ないことから高級食材としても扱われています。
Requirements include no rain, moderate humidity, and at least 10 consecutive days of clear skies. They are so rare that they are called a product of chance, and the amount shipped is less than 1% of shiitake production, so they hardly ever appear on the market. This is a high-quality product, with the cap of the shiitake mushroom cracked and the white cracks looking like a flower, as the name suggests.
It has a richer taste and aroma than regular donko, and is also treated as a luxury ingredient because it is distributed in small quantities.
