It's hard to know what to think about this one. Seven "floralscapes" went up in the LA area recently - they are essentially advertisements made out of flowers and plants planted along freeways. I don't know whether the idea originated from Toyota or from Caltrans, but the floralscapes here and coming elsewhere around the state, as well as Texas, are ads for the Toyota Prius. Toyota pays the state, which can obviously use the money, as well as covers the irrigation systems and upkeep. Caltrans doesn't allow any product identification in the floral murals, which keeps them more tasteful than something like actual product names or logos planted in flowers. I suppose as long as it doesn't become a slippery slope that does lead to that, it stays a win win, even if it does feel a little unnatural.
