Goponga Flowers are recurring enemies in Zelda series. They are often found in swampy areas and shallow waters.
The Goponga flower is one of the plants living in Goponga Swamp, around the mid-west part of Koholint Island. These flowers do nothing other than block your path. Even though they have no real attacks, these plants are dangerous and will hurt you if you touch them. If you have BowWow with you, however, he will eat the plants just like he attacks any other enemy. Using BowWow is the only way to make your way past them early in the game.
Once you have the L2 Sword, a spin attack will defeat the Goponga Flower. The Magic Rod, Boomerang, and Hookshot are useful weapons against these obstacles as well. There also exists a bigger variation of Goponga Flower known as the Giant Goponga Flower, which can fire fireballs at Link from a distance.

Goponga flowers are found in Spool Swamp in Holodrum. Like in Link's Awakening, these flowers are rooted to the ground, so they cannot move. The only different is they can fire fireballs at you from a distance and try to hit you with them. They cannot be defeated by normal means, so don't waste your time attempting to attack them with your sword. The easiest way to defeat them is by throwing your Boomerang or use Ember Seeds at them, which will only take one hit.
- "Native to the Goponga Swamp on Koholint Island, Goponga Flowers are hearty plants which dig their roots deep into the swampy soil. They are not very threatening, but they make travel through some areas of the swamp nearly impossible. When full grown, they become known as Giant Goponga Flowers. — (The Great Hyrule Encyclopedia).
