Here's an example of a business taking on street gardening. In this case this space is in front of the Restaurant Morandi and the Bakery @ Charles and 7th Avenue South. I'm not sure who is responsible for work but they have brightened that little triangle, which I don't know the name of (I'll check and report back later).
The triangle was previously somewhat sad. The benches were usually occupied by people you might not want to sit down with. Heavy chains with warning messages and pleas for respect now adorn the flower filled pits. Also window boxes have been added to the base of the flag pole. The pole itself sports a (unauthorized) yardarm courtesy of former Parks Department Commissioner Stern.
It's not the most thoughtful planting but it's an effort.
