Roselia is a Grass and Poison type pokemon.
In Pokémon Diamond, Roserade is no capable of learning additional moves or attacks however you can go to the Move Relearner in order to reteach it moves such as Weather Ball, Poison Sting, Mega Drain, Magical Leaf and Sweet Scent.
You can get a Roserade in Pokemon Diamond by evolving Roselia using a Shiny Stone. You can catch Roselia on routes 212, 221, 224, 225, or 229; or get it by evolving a Budew (through friendship), you can get Budew on routes 204 or 212, or Eterna Forest.
