Bomb Flowers are a recurring object in the Legend of Zelda series, originating in The Legend of Zelda: Ocarina of Time. They are a variety of plant that bears explosive fruit. Bomb Flower fruit can be picked and after a few seconds will explode, just like a bomb. Bomb Flowers typically grow in volcanic regions such as Death Mountain and the Eldin province.
Following their initial appearance the Bomb Flower later appeared in The Legend of Zelda: Oracle of Seasons and Ages (its first 2D appearance) The Legend of Zelda: The Wind Waker, The Legend of Zelda: Four Swords Adventure, and The Legend of Zelda: Phantom Hourglass.
After picking one up, they'll detonate within a few seconds, requiring the player to make use of it very quickly. Depending on which game it is the bomb will also explode if one strikes it with a weapon or engulfs it in flames.
The Gorons are viewed as the primary cultivator of Bomb Flowers, apparently specializing in them. They're known as their special crop. They're apparently very tough to root from the ground, though the chief of the Gorons and sage Darunia gives Link the Goron Bracelets, which will give its wearer more strength, thus allowing him to pick it up. While an adult, Link does not need to equip the Goron Bracelets in order to pick them up, as he is much stronger.
