Tried breeding a Roseraid with a Nuzleaf and I get a Roselia that doesn't know it. I can only assume it's because it's not on Roselia's Egg Moves list but kinda at a loss as to how to get it.
Breed a male Nuzleaf/Shiftry that knows Extrasensory with a female Roselia/Roserade holding a Rose Incense. The resulting Budew should know Extrasensory.
Note that you NEED the Rose Incense, since only Budew gets Extrasensory as an egg move.
