Those green fluttering leaves have frustrated Pokémon Go players from the beginning: Does it mean a Pokémon’s there? Nearby? Is it a red herring? From what we’ve been able to tell, those leaves indicate a Pokémon spawn point: If you hang out in that vicinity for long enough, you have a chance of seeing creatures not on your radar map appear. Note that I said “chance” — it’s far from a guarantee of a rare Pokémon appearing. Those leaves also don’t indicate the location of the current Pokémon you’re tracking on the Nearby list; don’t go chasing foliage in the hopes of catching that Drowzee.
