Answer 1

Diamond

In Diamond, Pearl, and Platinum, an elderly man appears on Route 228 in the Battle Zone, and will teach the move to all four fully evolved Grass-type starters. Various move tutors will teach Frenzy Plant to the fully evolved Grass-type starters if their friendship rating is maximized
