In Pokemon soulsilver where do you find orin berries?

Answer 1

If you mean ORAN berries, then you can get them, predominantly by going to the flower shop in Goldenrod City, which is next to the Gym. And the worker there gives you a Squirtbottle, you can then go North, through the National Park, using the exit that is to your right, carry on to the right after exiting and by the Sudowoodo (which is one of a kind in SS) there's another girl who gives you some berries, including ORAN berries, you can then use these in your berry case, and after watering them occasionally, they produce double the amount berries planted. :D ALSO you can get ORAN berries by trading the BLUE shard, with the juggler dude, who sits outside Violet City PokeCentre :) hope this helped and these can be found in any breakable rock (using rock smash) though these are quite rare, best of luck! :D
