The LA History Museum has a nice sized rose garden with rose bushes so huge. They have so many different kinds f roses there that it's really fun to look at. I also like that it's open to the public, so even if you can't afford to go to the museum, you can see the roses. One year, they had the butterfly house right next to it so you could enter the butterfly house and then exit to see all the pretty roses. It's a really fun bright spot in the otherwise modern city.
