Quick Answer
Day lilies are edible and can be prepared in various ways, including boiling, roasting, or sautéing their flower buds, leaves, and rhizomes. However, some species may cause allergic reactions or interact with medications, so proper identification and caution are essential.
Preparing Day Lily Buds
Day lily flower buds can be boiled or steamed like asparagus. To prepare, harvest the buds when they are still tightly closed, then rinse them under cold water. Remove the white base of the bud and slice the remaining bud into 1-2 inch pieces. Boil or steam the buds for 3-5 minutes, or until they are tender but still crisp.
Cooking Day Lily Leaves and Rhizomes
Day lily leaves and rhizomes can be roasted or sautéed like vegetables. To prepare, peel the rhizomes and slice the leaves into 2-inch pieces. Roast the rhizomes in a preheated oven at 400°F (200°C) for 20-30 minutes, or until they are tender and caramelized. Sauté the leaves in a pan with a little oil over medium heat for 5-7 minutes, or until they are wilted.
Safety Precautions
When foraging for day lily, it’s essential to correctly identify the species. Some day lily species, such as Hemerocallis fulva, are safe to eat, while others, like Hemerocallis citrina, may cause allergic reactions or interact with medications. Always consult multiple field guides and experts before attempting to forage for wild plants. Additionally, avoid eating day lily if you’re pregnant or breastfeeding, as it may cause uterine contractions or affect milk production.
