#DayLily's beautiful blossoms can be eaten now! Raw or lightly cooked, they offer a mild flavor with a mucilaginous effect. I love to tear the flower into smaller pieces and add it to salad or to garnish w/ it. The the long flowers buds and wilted flowers can also be eaten lightly cooked. Originally from Asia, and now widely spread throughout the landscape, this perennial's Latin name is Hemerocallis fulva of the Xanthorrhoeaceae family. BTW, occasionally may cause vomitting or diarrhea if eaten in large quantities by sensitive individuals.
