Description

Hemerocallis citrina commonly known as daylilies and night lilies, are among the most popular ornamental crops worldwide. In Eastern Asia, H. citrina is also widely cultivated as both a vegetable crop and for medicinal use. The unopened flower buds (fresh or dried) of the night lily are consumed as a special vegetable (also known as golden needle vegetable). The flower buds seem to be enriched with antioxidants, such as stelladerol and caffeoylquinic acid derivatives. These secondary metabolites are used to treat anxiety and swelling, and for other applications in modern medicine and biology.
