The cocash grows in wet grounds, and by the edges of small streams. The flowers make their appearance about the first of September, and remain in bloom until late in the autumn. The lower or radical leaves, especially about springs, and warm, sheltered places, continue green all winter. They have an agreeable, aromatic taste, with some astringency, and bitterness.
