As of Generation III, Frenzy Plant is the most powerful Grass-type move. It inflicts damage and then forces the user to recharge during the next turn. Unless this attack misses, the user will always have to recharge.
In Diamond, Pearl, and Platinum, an elderly man, much like the woman on Cape Brink, appears on Route 228 in the Battle Zone, and will teach it to the three fully evolved Template:Type2 starters of the previous generations, as well as Torterra. He will also require that the Pokémon that is to learn the move has a high happiness rating.
In Black and White, the Move Tutor that can teach Frenzy Plant appears in a house on Route 13, and will teach it to the four fully evolved Template:Type2 starters of the previous generations, as well as Serperior. Like in previous generations, this move tutor will require that the Pokémon he teaches the move to has a high happiness rating.
Torterra's body becomes outlined in green and it slams its front two legs into the ground. Giant roots with spikes on them come out of the ground and strike the opponent.
Venusaur's body becomes surrounded in an aura and it releases two energy beams from the sides of the flower on its back at the opponent. The beams twist around each other as they fire at the opponent. Eventually, the energy around the beams fade into two giant roots with large thorns on them, or two powerful and large vines come out of underneath the leaves on Venusaur's back and hit the opponent.
Mew, though repeatedly said on the Pokédex to be able to learn any move, is not able to learn Frenzy Plant because it can only be taught to Grass-type starter Pokémon.
In Pokémon Colosseum, this attack was erroneously named Solid Plant.
