- "A plant that grows in quieter areas of Hyrule. At night, it gives off a soft glow. Cook with it to increase your stealth."

Blue Nightshades are a Material from The Legend of Zelda: Breath of the Wild. These flowers can be found on the Great Plateau and other quiet areas of Hyrule. Blue Nightshade grows abundantly near Cotera's Great Fairy Fountain. Like other "Sneaky" materials, they glow in the dark and are easy to hunt at night. Twenty-four are required to upgrade the Sheikah "Stealth" armor set comprised of the Stealth Mask, Chest Guard and Tights. It also appears as a quest item in the Side Quest "A Gift of Nightshade".
Link can cook with Blue Nightshade to grant the "Sneaky" effect to dishes and Elixirs, which increase Link's stealth. As an herb, Blue Nightshade can produce both herb-based and vegetable-based foods. It can be a main ingredient in soups such as Cream of Mushroom Soup, Cream of Vegetable Soup, Creamy Meat Soup, and Creamy Seafood Soup; steamed dishes such as Steamed Fish, Steamed Fruit, Steamed Meat, and Steamed Mushrooms; other vegetable and herb based dishes such as Herb Sauté, Fried Wild Greens, Salt-Grilled Greens, Vegetable Omelet, Veggie Rice Balls; and Sneaky Elixir. Effects do not stack in cooking, so Blue Nightshade cannot be paired with items of other effects without resulting in Dubious Food. Blue Nightshade cannot be roasted or frozen.
