You can't tell, but these were in Okubo in Tokyo along Ome Kaido Avenue. Yeah, flowers pretty much look like flowers everywhere.
At any rate, despite the lack of water in California, people seem to be good with watering their lawns on a regular basis. This is somewhat irritating, but not nearly as annoying as the fact that the automatic sprinklers that they use to do so seem to spend as much of their precious liquids on the sidewalks as they do on the grass. I like to walk and it's very, very common to have to side-step sprinkler systems that are sending rivers of water down the streets and threatening to douse passersby.
In Tokyo, I never had to deal with this. Even in areas with artificially maintained greenery (such as the government building that was not too far from my home), they seemed capable of making the water hit the spots it was supposed to and keep it off of the ones it didn't belong in (like the streets and sidewalks). I very much miss the lack of obtrusive and wasteful lawn sprinklers.
