Daylilies are edible. The young green leaves are edible raw or cooked. Older leaves become fibrous. Tubers are also edible raw or cooked with a savory, nutty flavor. Young tubers are best, though the central portion of older tubers is also good. Steam or boil the tubers as a potato substitute, or toss them raw onto a salad instead of croutons. The flowers can be eaten raw or cooked. The petals are thick and crunchy, making very pleasant eating raw, with a nice sweetness at the base because of the nectar. They taste somewhat like fresh peas. They can be fried for storage and used as a thickener in soups and stews, or used as a relish. Leaves and young shoots can be cooked and used as a substitute for asparagus or celery. Take small shoots, strip away the larger leaves, sauté in a little garlic and oil, add raw to salads, or simply steam and drench in butter for a nice, crunchy treat.
